> There are some okayish cross platform frameworks, such as QT and even JavaFX. One of the main complaints of cross platform GUI's has been that they don't work like native applications. But for some reason nobody cares when the app works like a single page web app, which in many cases is a lot worse than even plain old Swing apps. Which at least supports right-click properly.

There's more to non-nativeness than just look and feel, which the more mature cross-platform GUI toolkits can ape fairly well. Another concern is accessibility for people with disabilities, e.g. blind people using screen readers. Qt, for example, is kind of accessible on Windows, Linux, and Mac, but not at all on mobile platforms. Not sure about the status of JavaFX. At least a single-page rich web app can be made accessible using the ARIA extensions to HTML, and if you use one of the big four web rendering engines, you can be sure they've done the hard work of implementing the underlying OS accessibility APIs well. Of course, many (most?) web developers don't implement ARIA for their custom UIs.

Accessibility is a point I didn't think about at all. Thanks for reminding me, it's really something that is all too often forgotten. JavaFX supports ARIA and all standard controls have accessibility built-in. But I have no expertise to actually comment on the quality of accessibility features in JavaFX.
