[pygtk] A design question

[John Ehresman]

Before you get into implementing widgets in python, look at using 
buttons w/ set_relief(gtk.RELIEF_NONE), ListView, and TextView, probably 
in that order.  This is not to say that implementing widgets isn't a fun 
exercise, but it's probably not the place to start.
