You surely don't mean that I could. :-)  But could someone on the 
Tutor list, the IPython-user list, or the python-win32 list? Good 
idea. I'll give it a try after a bit.

I dug up this paragraph from the new book on IPython due out in Sept. '08:
"IronPython uses .NET classes natively and seamlessly, and there are 
a lot of them.  Two of the gems in the collection are Windows Forms 
and the Windows Presentation Foundation, which are excellent 
libraries for building attractive and native looking user 
interfaces.  As a Python programmer, you may be surprised by how 
straightforward the programmers interface 
to  these  libraries  feels.  Whatever  programming  task you are 
approaching, it is likely that there is some 
.NET  assembly  available to  tackle  it.  This 
includes  third  party libraries for sophisticated GUI components, 
like data grids, where there is nothing comparable available for 
CPython. Table 1.1 shows a small selection of the libraries available 
to you in the .NET framework."
(The last paragraph on p.12 of the the free chapter 1 in PDF form:

Sure does! Thanks, Alan.
