Same thing for Qt Creator, although license may be an issue as always (although if it is then it's also probably not a problem, but I digress)

When I was a student, our teacher told us to just drag and drop GUI elements in Visual Studio and write the functionalities in C#. At that time I didn't knew that existed other ways to create user interfaces.

Winforms designer is pretty much it. But who's building windows apps these days :) ?
