Why not?

You seem to be all concerned about thread-safety, but the simple 
situation is that freeciv in general is not thread safe, so any 
GUI which uses threads will have problems.  The current GUIs instead
use event loops: events can happen in various orders, so you have to
worry about widget states and callbacks and network events etc, but 
each event will be processed one-at-a-time, so you don't have to 
worry about atomicity etc while processing for each event.
