most GUI mainloops are blocking, so after you start them you cannot issue
more commands from an interactive shell. Either you need to run a GUI
shell, or in the case of ipython run the GUI in a separate thread. One
exception to this is tkinter (tkagg), which plays nicely with a standard
python shell. I understand that recent versions of pygtk work also w/o
running the mainloop in a separate thread, but I haven't dug into the
details.

This question doesn't really make sense to me. Perhaps you can clearly
describe your use case (what you need to do) rather than the proposed
solutions.
