I think the OP was already talking about a ctypes based solution. If that's
all the OP needs, that's just fine, and will work out-of-the-box without
depending on things like a C++ compiler.

Regarding SWIG, you are definitely right about the "steep learning curve"
and the "complicated stuff". If you want to just get your work done, it's
usually better to go with Cython directly, instead of trying hard to make
SWIG do what you want. Because once you get to the "complicated stuff", you
will (hopefully) take the shortcut of rewriting your code in Cython anyway.
