I'm going to say something that is a bit out there, but to this day web frontend still feels like a downgrade in some ways to basic things Visual Basic had in 1998.
I was having similar thoughts about building UIs back in the late 90s and a few years thereafter. There were a number of tools, I remember using Tcl/Tk to create a GUI scheduling program that was relied on for many years. Later on we had Delphi and numerous others. I suppose building for the web was so much more complicated because the HTML/CSS/JS infrastructure was ill-suited as a basis for comparable GUIs.
