If you create windows (call GUI functions) in the same thread of the GUI 
main loop you have absolutely no problem, and your main program can run 
in parallel; if you use a channel carrying IO actions you can have the 
main GUI thread do anything you want (you send IO actions to it and it 
executes those); this might seem difficult but it's easy, surely easier 
than shared memory and locks or any other way to do the same thing 
(which is indeed considered very difficult for the reasons you cite). I 
am not sure if this is what you are looking for.

But is this the mailing list you intended to send your message?
