You could also use B4A (https://www.b4x.com/b4a.html https://www.b4x.com/b4a.html), which compiles BASIC into Java bytecode and has an interface builder -- as well as versions available for iOS, Arduino, and desktop Java. Only the iOS one requires a payment, the others are 100% free. The IDE runs on Windows. The whole thing was developed by one guy who is very active answering questions and providing lots of sample code.
