Can qWait not stay in the endprogramm?

If you want the real program to link to QtTest, sure.
Usually one doesn't want artifical dependencies.

I cannot cut qWait cause GUI stays unresponsive then. I would consider this as big problem...

Then I would suggest looking for a solution instead.

E.g. putting the result list into a model and having a QListView work on that model.
