I'd say that Javascript/Electron is easier if you come from a webdev perspective, from a tabula rasa point of view I highly doubt that the usual react/redux rigamarole that's often used is that easy. Not even sure if I like it that much better than ExtJS, and that's saying something. Same goes for Swing, I didn't mind writing in it, but the framework parts aren't really easier than Qt etc. Java as a language has fewer footguns than C++, so if you include that, sure... There's also FPC/Lazarus as a Delphi replacement (the original seems to be driven into the seventh layer of enterprise heck). Easy enough to create small-ish native UIs.
