There's nothing as good as VB6 that's developed and supported by *anyone*. It's not a Microsoft only phenomena.

I think programmers started wanting "real" languages (notice the quotes), and henceforth got more complexity and things take longer, although with GenAI, we may be back to the "draw as screen and do this" that we were with VB6. Just now the source generated should be considered the object code, and the prompt is the new source (at least for those types of apps)

I'm not sure how you define "native" here. If you mean native widgets then WinForms does what you want, is still fully supported, works on modern .NET versions, and Visual Studio still has all the GUI designers etc. WinForms is very obviously a calque of VCL, as well, so it can do everything Delphi did, but better.

If you mean native code then VB6 doesn't belong in this category (even if you compiled it to a standalone .exe it was still effectively bytecode).

I think WinForms with C# or VB is as good, if perhaps not as fun or approachable.
