For a frontend dev, it makes sense to use Electron for personal projects of this variety. You don’t need to learn another language, or even another set of tools, you just build the whole thing in-browser and get a shareable UI to boot.
Personally, I’m partial to the command line and to a lesser extent, TUIs, but I certainly understand building with whatever is most convenient and/or fun to the dev…especially on a personal project!
Full stack dev here, I work with c++ and other langs often and do work with web tech for clients, dcc scripts and plugins etc. This took me a few hours with electron because it's just js and I don't want a crummy cli, tui or generic gui look, I want something with batteries included that's easy to style, quick to add new functionality if needed (npm) and looks GOOD besides this isn't for anyone but me.
