I'm also surprised...The complexity of adding theming integration seems like a piece of cake, compared to WINE's core function (which is truly complex).
It only seems so easy. Wine shouldn't depend on GTK/Qt or anything else, controls should be drawn and work as much close to natives as possible.
Complete native themes support is enough here to treat this bug fixed. I don't know if generating .theme file + some registry data from Qt/GTK theme data is possible, but it definitely should be an external tool.
Personally I think such complexity isn't needed at all - there's a lot of important bugs to fix for controls, and this one has a very low priority.
