There is a VB6-like tool for the web! I know, because I co-founded it: https://anvil.works
I have ranted at length before on the reason that the Web is not amenable to RAD tooling. The short answer is that you have five different programming languages (HTML+JS+CSS+Python+SQL), with each component generating source code in another language, and that's impossible for a single development tool to manage sensibly.
To take one example: One of the best things about VB6 was autocomplete. But there's no sensible way to autocomplete what keys are in a JSON value that's been generated by a REST endpoint written in Python serving data from generated SQL, all with about 4-5 different frameworks in the way.
So for Anvil, we dispensed with that and did everything in one language (Python). Python on the front end, Python on the back-end, a Python-native database, a drag-and-drop designer producing UI components that are Python objects...and all of a sudden, it's all one representation and you can autocomplete it!
