At my last job, the app we were creating had both a web frontend and a Qt ui, so it was pretty easy to compare the relative difficulty of the two approaches since we were generally doing the same thing in both. Honestly it was kind of a wash. Qt was a little nicer as a developer because it meant never leaving visual studio, but I can't say that Qt offered some great advantage over HTML/CSS in terms of UI paradigm. I'm skeptical of this premise in that, yeah, the web isn't that great a development platform, but the alternatives aren't significantly better overall.
