I use Linux but since Windows still has the largest market share I will work on getting a Windows executable ready as well as a *NIX one. However this will probably have to wait untill Qt 4 comes out because then the Windows version will be licensed under the GPL.
Of course anybody is free to takle this problem, actually I would greatly encourage it :). You *should* be able to get everything to compile on a Windows system, even with the evaluation version of Qt.Please Note: You are still going to need all the 3rd party stuff mentioned on the download page.
