Best GUI option for VC++

Hi,

I need advice on what the best option for GUI development would be for a VC++ application. I have more than one function in my application that generates the same output in different ways. I want my GUI to be let the user choose any method to generate this output. What should I use? I heard about GTK+, but am not sure how easy it is to use on a windows platform. I have also heard of Borland's GUI tools but again, I don't want to stray away from VC++. What's easy to integrate into VC++ as well as being powerful?

Thanks for all ur help,
Kavi
