That sounds like Gooey: https://github.com/chriskiehl/Gooey, which creates GUIs for Python cli apps.

Autogenerated based on the args, but configurable and the widgets and menus can be defined in JSON.

Gooey is a great northern star to follow, but this hypothetical app should work with any command-line app.

Idea would be to define UI structure that outputs (and executes) essentially a string (command) to run.
