I had also written something similar 5 years ago when I had jumped from heavy GUI usage to Linux for some linux commands, byusing their man pages, semi-automatically. Interesting enough, now I value the reverse more and I would love to see the Yeeog.
Yeoog; Turn GUI programs into command-line
I too would love to see a Yeoog
I've used them all to good effect, but I don't think it's fair to call them similar to Gooey. They require a bit of tinkering to work and your script has to adapt to running with a GUI. Zero effort to turn your ArgumentParser into a GUI is really a brilliant feature.
