Of course OpenGL 2.0 is supported :) There's really nothing special
required from GtkGLExt (or similar libraries) for OpenGL 2.x support,
you just check the GL version and use OpenGL 2.x functions as usual.

For OpenGL 3.x, this isn't possible yet, as both "normal" and "forward
compatible" context creation for OpenGL 3 must be done a little
differently. Current GtkGLExt creation methods will give you at most 2.x
context. (See
