The most viable competitor to Electron other than Qt are the Java GUI toolkits. There are several but the two main ones are Swing (old, mature, not gonna win any prettiness awards but it gets the job done well enough in IntelliJ), and JavaFX (pretty darn good but people forget about it).
I've shipped apps using JavaFX before. It was quite a pleasant experience and I'd do it again in a heartbeat.
