to throw another option in the mix: we've done similar things using 
boost::python. We have a set of core rendering classes that do the slow stuff 
(iterate through long loops and pass the data to OpenGL) and the UI (PyQT) and 
OpenGL setups are done in Python.

Mixing PyOpenGL and C/C++ is no problem at all and works very well. I haven't 
used the C++ interface for Cython, but boost::python is very, very easy to use.

Just my $.02
