It is my understanding that the Windows version of Qt needs to be commercially licensed, whereas the X11 version is GPL/QPL dual-licensed. Have any attempts been made to port the X11 version to Windows so that GPL applications can be ported for free to Windows?

Not exactly. From the book:
1. Qt Free Edition. This is the UNIX GPL version. No tech support.
2. Qt Non-Commercial Edition. This is only for Windows and it is the full Enterprise package, free of charge (not GPL though). You can use this to create only non-commercial software. No tech support.
3. Qt Professional Edition. For all platforms and with technical support. It does not include some modules, like networking or tables or XML.
4. Qt Enterprise Edition. All platforms, all the modules with full tech support.

BTW, from what I see from the Trolltech download site, it seems that the Windows Non-Commercial Edition is only for the older version 2.30. They are now going fully commercial for the 3.x version of Qt on any platform except UNIX and Embedded Linux. Tue, 05 Mar 2002 01:48:00 GMT donotreply@osnews.com (Anonymous) Comments
