Compiling the source code.

I built GospelParallels using Python.  The ActiveState Python distribution is a very complete (and free) distribution on Python.  I like the completeness of this distribution.

You will need to download wxPython (which in turn has wxWindows contained therein).  wxWindows and the wxPython wrapper are a great UI for Python.

You can change the UI by hand, but I used Boa Constructor as the RAD building tool to create the UI.
