There is no purely fun way to build a production app. If there were everyone would do it. The hard part of building an app is the slog through the tedious parts. If you just want to build a toy app for fun, I recommend you just mess around with processing or pygame.

This! The fun of programming won't come out of a software project.

I find fun in programming by writing code solving small challenges. Something people really hate, e.g. LeetCode, is actually the fun place for me: I really enjoy writing some small size program to solve a made-up problem with my scattered time. I don't need to worry about language, library, framework, platform, UI, etc. The only thing matters is coding, and that's the thing makes me happy.
