Some time ago I did some tests on that behalf.

Trying to do a multithreaded GUI (i.e. accessing multiple instances of 
the OS'es widgets set from a single application) might be possible but a 
lot of hassle and dangerous indeed. But it does make sense, as you would 
allow multiple processors to work concurrently on the Library code (in 
the application) and the WidgetSet code (outside of the application)

Here supposedly the more promising way is to start multiple "display" 
applications and have them communicate in a decent way with a "business 
logic" application..
