Twisted seems to be missing in your list, a framework designed for 
asynchronous co-operative event-based programming.
Designed for writing network-communication programs (example chat servers), 
but it can deal with event-based GUI's with a few additional lines of code.

The basic idea is to wait for an event that 'something of interest' happened 
(like you do with GUI programming), handle the event, if necessary, set up new 
handlers, and wait again.
In Twisted "something of interest" is not limited to the GUI, but it can also 
come from a serial port, a network connection, another program, etc etc.
