Bloxorz game . how to move the rectangular block?

hello ,
I am developing the bloxorz game :

see this link :
http://www.albinoblacksheep.com/games/bloxorz

I have some how managed to draw the floor and a block on it. by taking two functions like this :

drawFloor present in Floor class outside main :

void Floor::drawFloor()
{

glRotatef(45.5f,1.0f,1.0f,0.0f);

//Draw floor
for(int i = 1;i<6;i++)
{


    for(int j = 1;j<6;j++)
    {

        //For hole to appear at 3,3
        if(i == 3 && j==3)
        {
            glTranslatef(1.0f,0.0f,0.0f);
            continue;
        }
    

    glBegin(GL_QUADS);
    
    // Top Face
    glColor3f(1.0f,0.0f,0.0f);
    glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.500f,0.500f,-0.500f); //top left
    glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.500f,0.500f,0.500f); //bottom left
    glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.500f,0.50f,0.50f); //bottom right
    glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f,0.50f,-0.50f);//top right

    //Left Face
    glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.50f, 0.50f, -0.50f); //Top front
    glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f, 0.30f, -0.50f);
    glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.50f, 0.30f, 0.50f);
    glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.50f, 0.50f, 0.50f);

    // Front Face

    glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.50f,0.30f, 0.50f); //bottom left
    glTexCoord2f(0.0f, 1.0f); glVertex3f(0.50f,0.30f, 0.50f); //bottom right
    

    // Bottom Face
    glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f,0.30f,0.50f); // top right
    glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.50f,0.30f,0.50f);  // top left
    glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.50f,0.30f,-0.50f); // bottom left
    glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.50f,0.30f, -0.50f);  //bottom right

    glTexCoord2f(0.0f, 0.0f); glVertex3f( -0.50f,0.30f, -0.50f);//bottom left
    

    

    // Right face
    
    glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.50f, 0.50f, -0.50f);  // Top right

    glEnd();

    glTranslatef(1.0f,0.0f,0.0f);


}
    glTranslatef(-5.0f,0.0f,-1.0f);

I have placed the hole at 3,3 position look on drawing floor.
My main problem is moving the block left and right . For that I have taken a structure called

typedef struct
{
public:

float x_pos;
float y_pos;
float z_pos;
float radian;

}cube_param;

I created an object like cube_param cube_pos;
while left key is pressed :

case WM_KEYDOWN: // Is A Key Being Held Down?
{
keys[wParam] = TRUE; // If So, Mark It As TRUE

        switch(wParam)
        {
        case VK_LEFT:
            {
                
                cube_pos.x_pos = - 1.0f ;
                cube_pos.y_pos = -1.0f;
                cube_pos.z_pos = 0.0f;
                cube_pos.radian = -90.0f;

                cube->drawCube(cube_pos);

                
            
            }
        }

        return 0;                              

        

    }

where drawCube(cube_pos); contains the same code as drawCube() but it has to move it.
Here does the structure cube_pos goes away with values to drawCube(cube_param cube_pos)

Look at it :

// For movement of cube
void Cube::drawCube(cube_param cube_pos)
{

float x_pos = cube_pos.x_pos;
float y_pos = cube_pos.y_pos;
float z_pos = cube_pos.z_pos;
float radian = cube_pos.radian;


//glTranslatef(1.0f,1.0f,0.0f);


glRotatef(radian,x_pos,0.0f,0.0f);


glBegin(GL_QUADS);
    
   // Top Face
    glColor3f(0.0f,1.0f,0.0f);
    glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.5f + x_pos,0.5f + y_pos,-0.5f); //top left
    glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.5f + x_pos,0.5f + y_pos,0.5f); //bottom left
    glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.5f + x_pos,0.5f + y_pos,0.5f); //bottom right
    glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.5f + x_pos,0.5f + y_pos,-0.5f);//top right


    //Left Face
    glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.50f, 0.50f, -0.50f); //Top right
    glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,-0.5f, -0.50f); //top left
    glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.50f,-0.5f, 0.50f); //bottom left
    glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.50f, 0.50f, 0.50f); //bottom right

    // Front Face
    glTexCoord2f(0.0f, 0.0f); glVertex3f(0.50f,0.50f, 0.50f); //top right
    glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,0.50f,0.50f); // top left
    glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.50f,-0.5f, 0.50f); //bottom left
    glTexCoord2f(0.0f, 1.0f); glVertex3f(0.50f,-0.5f, 0.5f); //bottom right
    

    // Bottom Face
    glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f,-0.50f,0.50f); // top right
    glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.50f,-0.50f,0.50f);  // top left
    glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.50f,-0.50f,-0.50f); // bottom left
    glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.50f,-0.50f, -0.50f);  //bottom right

    

    // Back Face
    glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,0.50f,-0.50f); // top left
    glTexCoord2f(1.0f, 1.0f); glVertex3f(0.50f, 0.50f,-0.50f); //top right
    glTexCoord2f(0.0f, 1.0f); glVertex3f( 0.50f,-0.50f,-0.50f); //bottom right
    glTexCoord2f(0.0f, 0.0f); glVertex3f( -0.50f,-0.50f, -0.50f);//bottom left
    

    

    // Right face
    
    glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.50f, 0.50f, -0.50f);  // Top left
    glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f,  0.50f, 0.50f); // bottom left
    glTexCoord2f(0.0f, 1.0f); glVertex3f( 0.50f,  -0.50f, 0.50f); //bottom right
    glTexCoord2f(0.0f, 0.0f); glVertex3f( 0.50f, -0.5f, -0.50f); //top right
    
    
    
    glEnd();

}

My idea is when left key is pressed i want to translate each and every vertex by adding or subtracting the x_pos,y_pos,z_pos present in cube_param structure
and then translate and rotate it. will it ultimately work for each and every move ?
If so how to do it.
