an approach to organize my python GUI application code?

A Python program consists of a script file (the py file you run to start
the program), and usually one or more additional module files (py files
that you import). The latter can be organized in packages, where
appropriate. There's also a search path (sys.path) that you can modify
in various ways (including from within the program) if you want to fetch
modules from different locations.

That's all there is; there's no header files or declaration files or
explicitly maintained object files etc; the program itself is just a
bunch of Python files.

To learn more about this, the "modules" section in the tutorial is a
good start:

http://docs.python.org/tut/node8.html

Looking at the structure of a few existing projects might also be helpful.

I would simply add that if your python script produces one or
more output files (for example a text or graphic file) you
might want to have an 'output' directory in your project.

Some people use a 'src' directory, but that is not nearly as
neccessary as in a complied language.

In Eclipse, if you do produce output files, make them
auto-refresh.

Thanks Ken and Fredrik for your direction.
