Delphi is also the first thing which comes into my mind when I think of that. I was also much more productive in that old days with GUI stuff. I also don't understand why there is no good RAD existing nowadays... I think the biggest reason is because there are no real solid non changing standards (like the Windows API and VCL in Delphi) and all this stuff HTML5+CSS3+ES6 have much more possibilities how stuff is created and interlinked to eachother in comparison to a Windows window system.
