I definitely recommend it. I used Cython to expose the core classes of an
in-house render engine I was developing in C++ to Python code and I can say
it was a breeze.

All you have to do is write a simple wrapper around your C/C++ code and a
pyx file that will compile your wrapper into a shared object. You can then
import the compiled .so from Python.

Wrapping C++ was a little more complicated than pure C, as objects had to be
used as opaque types in version 0.12, but now that version 0.13 is out, C++
support has been vastly improved.

Once you have your Cython module compiled, you can create an OpenGL
window/panel from Python code and the draw calls in your C/C++ code will
automagically work :)

Good luck!
