The VB6 IDE is distressingly easy to get running on modern versions of Windows - this is fortunate, since we still need to support it, but upsetting, since it diminishes the incentive for killing it off.
1. Modern .NET for desktop apps, whose many semi-obsolete UI frameworks make Java's UI tools look simple
2. Learning HTML/JS/React/Redux/CSS/Bootstrap/Python/Django/SQL/SQLAlchemy/Webpack...
Neither is likely to appeal to someone used to how easily applications could be created in VB6 or Delphi.
(I believe this so strongly I cofounded https://anvil.works, which is basically VB6/Delphi for the web. That's not so much a disclaimer, I guess, as putting my money where my mouth is :-P)
I don't see how Delphi + VCL is any easier than C# + WinForms, especially given that the latter is a GC language.
