Electron is slow and lethargic. Even the highly optimised VS Code makes me switch to gvim several times a day because input doesn't go in sequence; it seems to process easier input first rather than earlier input first. You can use Gtk to make executables on Windows and MacOS, but it's not comfortable and the resulting guis are ugly. They do not take advantage of the full provisions of the platform. Gtk is less cross platform, and more a foundational Gnome library that someone has ported to Windows and MacOS. No support for two major operating systems. Qt I can't speak to. WxWidgets seems to be a little .. dated. The screenshots on their website look like programs that were acceptable for a technical user 15 years ago. Has it moved on from that? Dunno. No support for two major operating systems.
