Recently, the maintainer of PyOpenGL has indicated that he's dropping 
Togl support (for Windows?) in the next release due to high maintenance 
requirements and limited usage.  Not to discourage you from working on 
Togl, but I therefore think Tk may not be your best long-term 
cross-platform solution for OpenGL + GUI unless someone is willing to 
take over python/togl maintenance in general (and on the Mac in specific).

I'm surprised you haven't had good luck with wx. Did you spend long 
trying to get it to work? How does the wxGLCanvas demo work for you?
