While some say Gates stole Windows from Apple, this is rather simplistic and not quite correct. Many were working on this vital concept at the time, including the NCSA, National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign with it's never completely realized X Windows, abandoned mainly because it was commercially obsoleted. NCSA developed the Mosaic browser, father of IE and Netscape/Mozilla and variants.

I do not know what a WPT is so I cannot verify that part of your query.
