Programming your application or library based on Qt has always had the promise that you can deploy your application on many different platforms. Development of those applications can, likewise, happen on many different platforms. QtCreator runs on Windows, Mac & Linux among others.

Albert Einstein has been quoted as saying that “insanity is doing the same thing over and over again and expecting a different result.” Apparently this is a misquote, and the original quote actually belongs to Rita Mae Brown, but that’s not important right now.
