Of course "in general" this is correct.
But I understand that it should be possible that an application (using
additional threads) creates more than one "Main Frame" by attaching to a
new "instance" of the Widget set and thus - regarding the GUI - acts as
multiple applications,
You cannot have multiple instances of an widgetset, and not multiple
(different) widgetsets in one application.
What should be feasable are windows (forms) in more than only the main
thread, when every thread uses its own message queue. Then a worker
thread could e.g. update its progress indicator, in his own form,
without blocking (or being blocked by) the main thread.
