Do you need twoWindows in two seperate threads? You probably can acheive
what you want by having one GUI thread and one worker thread.

Take a look at the thread examples in the glibmm documentation:
http://www.gtkmm.org/docs/glibmm-2.4/examples/thread/
thread.cc shows the use of thread, mutex and condition
dispatcher.cc shows the use of a dispatcher to communicate from a worker
thread the main thread (e.g. your GUI thread)
dispatcher2.cc shows the use of dispatchers to communicate back and
forth between a main thread and a worker thread with a GLib MainLoop
running in it.

You probably could also start a new window in a worker thread (which
comes with its own main loop). But I am not sure about this.
