For Tcl/Tk, there's vTcl which resembles Visual Basic 3.0 (for Windows) as far as laying things out. It supports all three of Tk's geometry managers (grid, pack, place) and you can simply drag-and-drop your way to a GUI in seconds if you're into that kind of thing.

Further, there are several experimental projects that support running Tcl/Tk over HTTP/HTML rather than X11, Win32, SDL, the current Mac OS X/macOS GUI system.

TkWeb and WubTk are examples of this.
