For comparison of ctypes and SWIG wrappers of a simple C++ codebase, feel free to take a look at the code for scikits.ann (http://scipy.org/scipy/scikits/wiki/AnnWrapper). The original wrapper was written using SWIG and the numpy typemaps. Rob Hetland has coded an almost-the-same API wrapper using ctypes which is linked from the above wiki page. Perhaps it will help the OP to see a similar project side-by-side.
