Is there a reason not to write the entire GUI in Python and use
Tkinter or wxPython?

Sounds like a platform-specific issue; since you mention .exe files,
I assume you're running some flavor of Windows.  One can certainly
run .py and .pyc files from a Tcl/Tk script on Unix-like systems.
What does your code look like?
