"""
The basic idea here is to wrap a Python function (in the case below, it is
``do_programming_crap()``) and make a basic GUI interface to call that
function.

Theoretically, it's much easier to create a packaged executable which is only
dependent on Pyramid vs. depending on something like PyGTK, WxWidgets, Kivy,
SDL, whatever.
