critique my code, please

Just a few suggestions:

1) use consistant formatting, preferably something like:
  http://www.python.org/peps/pep-0008.html
  E.g.:
yesno = {0:"No", 1:"Yes", True:"Yes", False:"No"}

2) if (isinstance(self.random_seed,str)):
             s=s+"Random Seed: %s\n" % self.random_seed
         else:
             s=s+"Random Seed: %d\n" % self.random_seed
  is unnecessary, since %s handles any type.  Just say:
   s=s+"Random Seed: %s\n" % self.random_seed
  without any if statement.(unless you need fancy numeric formatting).

3) I would strongly discourage using print statements (other than for
debugging) in a GUI program.  In my experience, users fire up the GUI
and close (or kill!) the parent tty window, ignoring any dire messages
printed on stdout or stderr.  In a GUI app, errors, warnings, any
message
should be in popup dialogs or in a message bar in the main window.

4) If you want to be cute, you can use
  s += 'more text'
instead of
  s = s + 'more text'

I'm not a wx user so I can't comment on the GUI implementation.
Good luck!
