Errr, not at all. 

The user interface in OSX is drawn using Quartz*2D*. OpenGL is only used
by the QuartzCompositor, which combines windows content from all
applications and enable funky effects (drop-shadows, scaling,
translucency, etc...).

So the widgets you see are *not* 3D. They are just a bunch of 2D pixels
mixed together through an OpenGL pipeline to speed up the whole damn
thing a little bit.
