Different Shaped Windows?

[David Oppenheimer]

Dear Group,

>From a posting in another  newsgroup, I am told that you can:

=====================================
"create windows that have different shapes than the
ordinary "square" ones. You can do than thanks to the "regions" : What
does
that mean?
In Win32 you can define regions and than assign them to already created
windows. For example:

SetWindowRgn(handle, CreateEllipticRgn(0,0,100,200), true)

will create an elliptic window. MSDN has more info about regions. You
can apply all sorts of operations to your regions like intersection,
addition, etc. to obtain different shapes.
=================================================

Question is:  Can this same task (creating a non rectangular window) be
accomplished with any of the GUI toolkits available to Python such as
Tkinter or wxPython?
