Ehh, I dunno, it was really, really popular back then. I would bet that a non-trivial number of apps were built using VB by actual software engineers. Couldn't find concrete numbers but this article claims at its peak, 2/3rds of all business apps on Windows PCs were in VB:

I messed around with several other UI toolkits of that era -- AWT, Swing, Qt, Flex/ActionScript -- and none was as productive as VB for simple apps. It was just the right amount of simplicity and development velocity for the myriad simple use-cases that were perfectly happy with rigid layouts.
