I think if you are going for native widgets with a more lightweight (and more liberally licensed) bent, then wx is a solid option too, though it requires a bit more manual UX work, even though it uses native widgets for real (even in some places Qt doesn't). But other than Qt or wx, I really can't get behind these new GUI platforms which keep cropping up. They all have too many issues and don't end up presenting a native experience (or often even a good one).
