Scrolling a frame is a bit of a nuisance because frames don't have the
necessary scrolling methods to start out with the way that canvases,
for example, do. It's perfectly possible to do but requires a bit of
work. Happily, you don't have to do the work because Greg McFarlane
already has. His Pmw (Python megawidgets) is very handy. It's at:

http://pmw.sourceforge.net/

It includes useful widgets such as ScrolledFrame, ScrolledText, and a
bunch of others. Another handy thing (though not directly related to
your question) is Fredrik Lundh's An Introduction to Tkinter. It's at:

http://www.pythonware.com/library/tkinter/introduction/index.htm

Between the two, they make Tkinter programming much easier. If I had
a bunch of messages to display, I'd look at sticking them in a
Pmw.ScrolledText and plan to live happily ever after.
