You mentioned using SWIG, but I'd actually suggest using Cython instead. It 
will make it a lot easier (and faster) for you to convert data types 
between Python and C/C++ (and will also allow you to skip over most 
ref-counting problems). Since you appear to know C++ anyway, you should be 
able to get comfortable with it quite quickly.
