According to the spec, glCreateProgram returning zero indicates that an error, but I could not find a list of possible errors.
Since it does not have any arguments, my best guess is out of memory? (That would be very strange tough)

What does glError( ) return?

Are you sure you have a valid context?

Check whether

   esInitContext ( &esContext );

and

   esCreateWindow ( &esContext, "Hello Triangle", 320, 240, ES_WINDOW_RGB );

return successfully.
