Logically, it's typically the GUI that depends on the
underlying logic, while the logic could be utilized in
a non-GUI context, maybe in a CGI-script, or as a
library module in some larger program.

Also, automated unit tests are always a good thing, and
they are much more complicated to do with a GUI.

Thus. I try to keep my logic independent from any user
interface code (be it GUI, Web UI or anything else) and
to make a thin GUI layer that imports the logic.
