I was also looking for examples of this and i found really hard to find 
any. Did you find any good Tk based  examples?

there is an example on the wxpython documentation.
This might also help, but i am not sure it is very right.

If you are just interested on simple 2D graphics you might find this 
useful, we are working now on it and it comes with a GLUT example but it 
can also be used in wxpython.

It is still very early in the development though.

We are aimed to do exactly what you describe in this last list, and it 
is kind of working but it is not very good code, just a prototype, we 
are trying now to organise it in a sensible way with the help of a Java 
game programmer who kindly has offer his help.

But as i said it the example that  comes with it is based on GLUT, if 
you really need it i could send you the wxpython prototype but it is 
currently under construction so it might not work very well

best
