The irony is, Qt _IS_ a cross-platform GUI, where you build your UI once and it looks like Windows on Windows, Mac OS on Mac OS, and the look of whatever window manager on Linux.

Looks like, yes. Behaves like, not really (at least on Windows.) The few Qt apps I have certainly do not feel as responsive as the native ones, despite (mostly) looking that way, so it is rather awkward. They're noticeably laggier even in simple operations like displaying a menu, or responding to window resizing/moving.
