An alternative to sip, particularly if you're really familiar
with C++ (and in particular with its awesomely powerful templates:
they use signature-based polymorphism, just like Python, and
thereby give C++ a fraction of Python's power!-), is Boost
Python, part of the superb Boost set of libraries.  See
http://www.boost.org/ for more -- but you do need a decently
updated C++ compiler, such as VC++6 or a reasonably recent
version of gcc.  If you and/or your compiler would rather
avoid templates, Boost is probably best avoided too:-).
