Similar experience for me. I've been using it to make Qt GUIs, something I always avoided in the past because it seemed like a whole lot of stuff to learn when I could just make a TUI or use Tkinter if I really needed a GUI for some reason.

Claude Code is producing working useful GUIs for me using Qt via pyside6. They work well but I have no doubt that a dev with real experience with Qt would shudder. Nonetheless, because it does work, I am content to accept that this code isn't meant to be maintained by people so I don't really care if it's ugly.
