During installation it was that wxpython would only look for pyton2.5 in the register, that was using all the latest dowload links from the python page. Put python2.5.2 on and it seems to be working now. They do say to use 2.6 but they haven't updated wx perhaps.
Anyway, your app loads, opens the tgd, changes settings, creates tile etc. But when I hit render, no successful renders out of n renders. Using the batch option creates the batch files for rendering in the same location as the tgd. Is there a line in one of your files that points to the TG2 installation folder? If I were to render with your batch files, how do I? In the command line text it says how to do it with a tgd file, is it similar?
