UI toolkits (like "tk" and "gtk") usually use a so called event loop
which gets information about user interaction events
(e.g. keyboard/mouse events) and dispatches appropriate application callbacks.
When you use two (or more) such toolkits in the same application,
you need a special event loop which multiplexes the events
to the various toolkits.
The implementation of such a multiplexing event loop might
be difficult (and likely will be dependent on the UI toolkits
to be integrated). Therefore, if possible, try to avoid
combining multiple UI toolkits in the same application.
