WTL is, spiritually at least, what the MFC team would've come up with had they started with the C++ language as it is today. It's an extension to ATL and available as a download from Microsoft.

If you have trouble downloading WTL, see Petr Prikryl's "Easy Installation of WTL" post on the Code Project site.

WTL is pretty much completely undocumented, but you can read about it in a 2-part series by Chris Sells, Dharma Shukla and Nenad Stefanovic (chief engineer on WTL at Microsoft):

1. WTL Makes UI Programming a Joy, Part 1: The Basics

2. WTL Makes UI Programming a Joy Part 2: The Bells and Whistles

You can also read about WTL on iDevResource: WTL Architecture by Dr. Richard Grimes. 

WTL is officially unsupported, but the ATL mailing list has lots of coverage of WTL.

The CodeProject is gathering a set of WTL resources at www.codeproject.com/wtl.

Yahoo has a WTL newsgroup.
