All parts of the software have to be licensed compatibly with the GPL. The FSF
has a fairly comprehensive list of the licenses they believe are GPL-compatible.
The source that you provide needs to be the preferred form for making
modifications; i.e., you can't use a tool that obfuscates the code. You need to
provide the scripts that you use to build the software. You have to be careful
about using patented techniques in your code. The source code must be offered at
no extra charge (this part of the license is a bit tricky, so please read the
license and the commentaries).

You probably won't have to mess with lawyers, but with all software, even with
wxPython and PythonCard, you yourself should understand the legal implications.
You said that you "do not fully understand this license stuff," so I am trying
to give you the resources such that you can learn.
