I have a feeling that you do not have any actual experience with Qt Designer or RAD tools? Designing a user interface quickly is many times easier in Qt, Delphi, etc. than in HTML/CSS. It start with the basic fact that Qt has many useful widgets that are not available in plain HTML, nor many CSS/Javascript frameworks. From there it is just drag and drop, adding a few spacers here and there and you are done. I have a fair bit, albeit less than the average user of said programs, of experience with Qt Designer and, admittedly to a lesser extent, Delphi. They're infinitely more complicated than, say, Adobe Muse. Muse has plenty of widgets, too; even if it's not 1:1 on pure quantity. BlueGriffon is quite nice, too. Why would I develop in such an arcane manner if I already have great development tools for more than two decades? Modern web browsers* have more or less functional IDEs within their devtools. *Except Firefox, of which has devtools half a mile behind most other browsers, at least in my opinion. Of course, I'm speaking from the point of view of someone who's a much worse programmer than designer.
