We had a legacy application using MFC/C++ and no one anymore likes MFC at the studio, so we had to either somehow switch to C#/Windows.Forms|WPF overnight or slowly move to something else. Since there is MfcMigration toolkit for Qt - slow progress was the choice - so every week less and less of MFC is visible, and more and more from Qt. Other toolkits can benefit if there is a transition layer - or at least something where you can plug into the existing message pipeline, windowing system - and then start replacing widget by widget, dialog by dialog.
