You can run multiple windows, or one window with multiple panes, in one 
thread with one event loop.  Best to do gui stuff in the main thread and 
only use other threads for things that would block.  I see that you 
already know how to use .after to loop.  You can have multiple .after 
loops, with different delays, in one thread.
