Windows still has Windows Forms with C#. Download Visual Studio Community edition for free (not VSCode), create a new forms project, and you'll have a GUI in minutes. Even beats VB6 in areas like automatic resizing because it has better docking support. It'll only target Microsoft's proprietary .NET but because Mono has supported that forever, you can run those applications anywhere Mono exists. There are also tools like Gambas and Gnome Builder that'll let you drag and drop UI components, but I find the software designed to run on Linux kind of lacking in comparison.
