I don't know why WxWidgets seems to be less popular now than it was back then. I remember it being somewhat popular. Now people hardly seem to know about it.

FLTK looks horrible next to most modern applications. But FLTK 2.0, which has been abandoned for 10 years, actually looks pretty modern and the API is actually pretty elegant. There was some kind of split in the community about FLTK 2.0 breaking backward compatibility and I guess the 1.0 people won in the end.
