Yes and no (of course). The underlying Tk to Tkinter if very
efficient; I've see 100,000 line Tk programs running in 8M virtual
under Linux, which is pretty amazing for an interpreted language.

You have an alternative with Tkinter if you find your application is
getting too memory consuming. As a rule, a lot of UI code is modular
and self contained, so if you don't mind mixing languages, you can
code self-contained UI portions directly inTk, and call them from
Tkinter. You'll be able the Python overhead on the Tk code that
is never used by Tkinter.
