Pierre,

thanks for posting this.  I wasn't aware that it is possible to use the
Python.NET extensions to make a Windows GUI for python code.  Cool!

For the py2exe issue, CLR.dll seems to replace Python's __import__
function with its own, but your recipe works fine.  Maybe it should go
into the py2exe wiki?
