The good news is that it's possible, and very rewarding once you get
it working.  The bad news is that it's gonna take a few hours to get
everything set up.  Robin does have the exact version of SWIG that he
used in a download somewhere... you don't have to build it.

First thing is to use swig 1.3.27, plus some patches that are in the
wxWidgets source.

Here's my write-up of how I did it with Visual Studio.  On the mailing
list there's a setuptools method too...
