In Dezember 2002 Holger Schröder started a native win32 port using a Qt2 release. His mainly intention was:

"This is not to fool the Trolltech people, they are really doing a great job. I think, that as well as many kde programmers use Qt for commercial projects at their companies and generate income for trolltech this way, Qt on windows will convince more people to use Qt. Imagine you could use konqueror, kmail, koffice and kdevelop instead of internet explorer, outlook, ms office and visual studio at no cost and even develop gpl`ed programs with that for free.
As kdevelop recently was mentioned as the best ide for linux beating kylix besides others according to a dot.kde.org article, i guess we could convince quite some people not to use .net and switch to Qt for their next projects. but let's see how far we will come."

After Holger has finished his analysing work, he started implementing important classes. As a result the t14 example (a little game) was runing native on win32 environments. It had many open issues, but the initial work has been done. In the beginning of 2003 Holger has got a job with access to a commercial Qt license, which does not allow him to work on this port anymore.

In the beginning of 2003 Richard Lärkäng took over the development of the Qt2 port. After diving very deep in the Qt classes and working on some import classes like QApplication, QCursor, QPixmap, QWidget and other, in Juni 2003 he switched over to the Qt 3.1.0 release. After porting some classes and fixing some open issues he applied (and modified) the patches to the Qt3 cygwin release. At the end of 2003 Richard Lärkäng stopped his porting work.

In the time of Richards work Ivan de Jesus Deras Tabora contributed some very good gui related patches.

In August 2004 Christian Ehrlicher, Andreas Hausladen and Peter Kümmel joined the team. They fixed bugs, added borland and several msvc based compiler support, added registry support, fixed unicode support and several other important things.

In October 2004 Thiago A Correa and Simon Rutishauser joined the team. They fixed msvc project file generating and printer support.

In the late 2004 Chris January cleaned up the code, fixed bugs, cleared licensing issues and contributed several other important things.

In Juli 2005 Trolltech released the first sources of the gpl'ed Qt4 on windows. Christian Ehrlicher takes the sources, added msvc and borland support and released an addon package for the Qt4 releases on windows.

Currently Christian Ehrlicher provides msvc suppport and Andreas Hausladen borland compiler support for the Qt releases.
