what library to use ?

Ï’m looking for the most easy way to build a windows 9x/NT (maybe linux also) application that enables a user to select predefined objects (like kitchen equipment / furniture) and place them on a canvas. Then when the composition is ok a perspective view should be made.

As I understand several libraries are there to deal with specific tasks like games etc.

What library should I do this with ?

I would suggest to use GLUT and OpenGL, for portability. If don’t need complex input functions, GLUT will do very well. Also it will take care of all the windowing issues.
