The easiest answer is "don't do that". In general, you're going ot ahve 
a much easier time in a python embedded project using the same GUI 
toolkit for C++ and python. wxWidgets+wxPython, for example.

Why do you want to use TKinter? why not use the Carbon stuff from Python 
instead? MacCVS is not cross platform anyway. Another option is to see 
if you can use PyObjC and Cocoa, though I don't know how hard it is to 
mix Cocoa and Carbon.

In the long run, your best bet would be to make a cross pl;atform app 
with wxWidgets or QT, or make a Mac app with Cocoa, but that may be more 
change than you want to deal with...

There are also other efforts along these lines anyway, at least for 
Subversion. See:

RapidSVN  for a wxWidgets version: http://rapidsvn.tigris.org/
SVEN for Cocoa version: http://www.nikwest.de/Software/#SvenOverview
PySVN for a wxPython cversionhttp://pysvn.tigris.org/

There are WAY to many SVN and CVS clients under development, I'd love to 
see more collaboration. I wouldn't put much work into a CVS client 
without having Subversion support in mind anyway.

By the way, I think there is some relvance here to our recent discussion 
about X-platform toolkits. If you are writing a SVN or CVS client, you 
are writing "just the GUI part". The functional code is developed 
separately. And yet, there is a LOT of work to do to write a good GUI, 
and it has to be done differently for each toolkit used. It still might 
be true that to get the best possible Mac client, you'd want to use 
Cocoa, rather than wxWidgets or QT, or ..., but it's clear that there is 
a lot of extra work to do when you make that choice. Fortunately, there 
are a lot of people that want to write SVN and CVS clients, so maybe we 
will get really nice native clients on all platforms.
