I'm open to either approach.  I don't know a lot about JNI, so I was 
hoping somebody would come along for the ride who could answer certain 
questions about how SWT is implemented.  A third option would be to 
grovel over SWT and implement an identical functionality in Python 
(pure-python plus ctypes), and make a mirror implementation, rather 
than a wrapper.  What approach we take depends largely on who shows up 
and what they feel comfortable with.

The API is identical for each platform, however, so depending on the 
level at which you wrapped it, this is only a build problem.

Yes, JVM-less CPython extension would be the plan.
