Of course it's possible. But it also depends on just what you're talking about. WP and Joomla are frameworks/engines ... VB6 can also be the same, and be used server side to serve up the HTML to the client browser, as long as the server allows it. But if you mean using VB6 to build an app that helps you build HTML files that you upload, it can do that too, they're just text files. I built a semi-WYSIWYG HTML editor back in 95/96 using VB4... that's how I learned HTML and how to build web sites.
