What are some *slick* UI libraries/frameworks/tools for, non-MFC, Win32 C++ apps? [closed]

Question

What is a really good Windows, C++, UI library, framework, or tool that will allow me to very simply and easily add a slick look & feel to my native C++ win32 application?

Also;

• Slick means skinnable with window background images, fancy buttons, shadows, all that jazz.
• This is non-MFC
• Supporting Windows XP and beyond
• Royalty free licensing (we expect a lot of installs)
• VS2008

Qt has all you are asking for.
