I don't know what project you have in mind but what about targeting an older platform? If it's purely for fun/satisfaction try making an Amiga or DOS program. Plenty of emulators for modern platforms to help you run it on a Mac or Windows machine.
Depending on your project one route to consider is to build your UI with an immediate-mode style library (or write one yourself, it's not terribly difficult). You'd be sacrificing accessibility likely but it would get something out there fast that's pure code and doesn't require a ton of fiddling to get going.
Another "fun" area is to try Common Lisp or Emacs; both have options for UI and graphics programming and all usual facilities on modern systems. The benefit is that you can stay in warm-and-fuzzy parentheses and get a highly interactive development environment that you rarely have to leave.
