It depends. There are good wrappers out there, I personally prefer SIP.
However, a mixed language environment is always a PITA, especially for
distribution.

If you can, write everything in python. Identify bottlenecks, and if you
must, I suggest using C + ctypes for performance-critical code.

Obviously it's a matter of taste, but C++ is a beast, and getting it to work
seamless under varying compilers and OSes could be avoided using plain C.
