This is fairly trivial, and what most applications do.

It should work on windows with very little modification. The problem is that 
very few windows applications use OpenGL.

Getiing basic OpenGL working is fairly easy. The tricky bits are:

- Multiple contexts.
- Window manager integration, and cliprects.
- OpenGL extensions, particularly if you're going to be migrating between 
different hosts..

You may want to take a look at gallium[1].  I expect that will provide a 
better medium term solution than opengl, especially if you care about 
windows/Direct3D.
