Do you even know what RAD means?
20 years ago, RAD meant that you could drop visual components on a form, add some events, set some properties, and hit the green run button to compile and run it.
A very visual way of programming.
QtCreator with it's visual designer comes close, but then you have to suffer a more unforgiving syntax (C++), a complex macro compiler (MOC) and not at all easy cross-compilation / distribution.
