Funny enough, I have written a piece of a web application in C, connected by JNI. It's even easier with CPython. Certainly, you can't do that with client-side JS, but could you imagine mixing desktop-side JS and C++ in the view? That said, the piece that is in most need of performance in a desktop application is often the GUI itself. Imagine Microsoft Word taking a split second more when it updates the ribbon, for example. Perhaps there is an exception for desktop apps that need direct connections to hardware.
