Problem is, to be graphical and portable, you need wxPython also so
sizewise 90% of the install is already done. ;-)

Unfortunately, a Windows-native installer is required for this inital part. I 
would
recommend the NSIS installer which is totally scriptable and can execute other 
programs
(such as Python scripts) for the final configuration steps.

I assume you are just writing an installer for the client only. For the server, 
users need
Cygwin, which has its own (pretty good IMHO) installer and package system, I 
suggest we
just write a 'gnumed' package for that system.

One final suggestion: don't use environment variables such as PYTHONPATH to 
tell gnumed where
to find modules. Windows has a 128-byte limit on the size of the environment 
(same as CP/M). 
Use the Windows registry, or write the gnumed.py script at install-time
from a template with the correct paths embedded.
