There's apparently a tool called Umbrello, though it is a KDE-specific
toolkit, it apparently uses an XML format that's common to UML modellers.
http://uml.sourceforge.net/index.php
I know this isn't platform independent, but perhaps the XML format is
"portable" between UML modelling applications that are available on Windows?
That, or run Umbrello on a Un*x box, using the built-in Aqua X11 tool on
Mac OS X, the Free software XFree86/KDE3 on Un*x or a commercial product
like XWin32 for Windows (there's probably a XFree86 version available
for Cygwin under Windows if you look).
