I think he's looking for toolkits of widgets that look exactly as if they came straight out of the latest MS VS2005 or MS Office products, more than what the basic Qt widgets provide, so that he can put them straight into his application with a minimum of change. Sure, Qt has docking windows, tree views, WindowsXP styles, etc., but there are still some tiny differences that a trained eye can spot between Qt and Windows widgets. And Qt has lots of power to further customize the look and feel like that, but I think he is looking for someone who has already done the work. Are there such toolkits built on top of Qt? It seems like a potentially lucrative market, if there aren't any...
