A few other differences: - The classic desktop GUI frameworks (Qt, wxWidgets, MFC, Swing, WinForms, etc) are based on a completely OOP inheritance and ownership model. You are responsible for instantiating widget instances, configuring them via setters, appending them to parents, and likely cleaning them up as well. - It's been long enough since I've done desktop GUI dev that I can't speak to the state management aspect much, but I can certainly say that at the time, my own programming understanding was limited enough that I would have said my "state" was "whatever items are currently inserted in that ListBox". (I knew that forms of data binding existed, but didn't grok them yet.) I do remember Swing's JTable widgets have a distinct MVC setup, at least. - Web dev is _heavily_ concerned with the number of bytes being delivered over the wire, so it's not just the number of round trips, there's the obsession with trying to find the tiniest library that can do what you need (combined with the nonexistent JS standard lib). With the desktop? Who cares, let's link in 50MB of Qt DLLs! (yes, yes, insert Electron joke here.)
