I've started doing this for a Go game i've been (re)writing. The key was
to make the main "Gui" class have it's own thread, and have
implementations of a "Gui" add the necessary foo in the Run() that is
used when the thread runs. Here's a snippet from my GtkGui.cs:
      protected override void Work()                                  
      {                                                               
              Application.Run();                                      
      }                                                               
                                                                      
      public override bool Init()                                     
      {                                                               
              Application.Init();                                     
              Window win = new Window ("Testing!");                   
              Button button = new Button("Push Me!");                 
                                                                      
              win.DeleteEvent  +=                                     
                      new DeleteEventHandler (OnWindowDelete);        
              button.Clicked +=                                       
                      new EventHandler(OnClicked);                    
              win.Add(button);                                        
              win.ShowAll();                                          
                                                                      
              return true;                                            
      }
</snip>

Work() overrides the virtual function that is called when the thread is
started. That way my console/spawning program uses Reflection to load
the dll, instantiate the class, and then kick it off. There may be other
ways to do this without creating a seperate thread for the loaded GUI.

HTH,
