[Pythonmac-SIG] problem importing OpenGL.Tk

I downloaded wxPython, and played with the demos from RunDemo.
I tried the wxGLCanvas demo.  Seemed a little balky to get the initial
image in the window, but then seemed OK.  (Balky meaning the rendering
window starts blank, and I have to generate a bunch of mouse events
before anything appears).  Next step for me is to experiment some 
my own data.

Any helper apps for translating Tkinter to wxPython :-)?
