twinBasic.com is a revamp of VB6 using current tech
it's this a niche for some industry? or all those products are aimed at people's nostalgia of running their old programs?
these tools could be the modern vb6, having modern UX paradigms such as responsive design etc... yet it is just producing something one would use only for nostalgia or explicitly support for a niche market still needing actual vb6... which i didn't know existed till now.
Given that there are already other, more modern, languages and frameworks that do you want you describe I don't think there is a market for that kind of modern Basic. That's why nobody has done it.
