Some applications will open new windows, but very few actually literally
clone themselves.  If you actually want to replicate literally
everything that your app is doing, you can use any one of the process
starting mechanisms to spawn a new instance of your application (you take
command-line arguments, right?)

On Windows, you can use os.system('start "" <command line>') (be careful
with argument quoting...). On other platforms, you may be able to
os.fork(), though I've never tried it with wxPython applications.  May
be an interesting experience.
