yep -- you can do this.

You may want to try using Cython, rather than raw C. Some googling 
should tern up some notes on this. In particular I believe Sturla Molden 
put out a *.pxi file for OPenGL:

In fact, at least some of PyOpenGL is written with Cython.

well, I don't know that I'd do it for this reason -- if you pull/push 
the data as numpy arrays, you can do all that without data copying, so 
keeping it in Python may be fine.
