Swig is probably your best friend here.  I wrote a python interface
to the Matrox Imaging Library (i.e. for the Matrox Meteor frame grabber)
in a couple days that was essentially complete.  Of course, 
the Matrox Imaging Library has a coherent API, whereas VFW doesn't...

I can send you my SWIG .i files for the Matrox interface,
as well as some C++ code that uses VFW.  The C++ code is not
for a standalone app, unfortunately, it is a VTK class (and
I doubt that you want to build VTK + the VTK/Python interface
simply to grab an image into a Python string though that is
a possibility).
