Windows WTL

Windows Template Library (WTL) is a C++ library for developing Windows applications and UI components. It extends ATL (Active Template Library) and provides a set of classes for controls, dialogs, frame windows, GDI objects, and more.

Here is a link to an excellent CodeProject tutorial. Only the first part is linked to since at CodeProject it is real easy to navigate through a article series. (If it only could be that at MSDN as well...):

1. WTL for MFC Programmers, Part 1 - ATL GUI classes, written by Michael Dunn at Codeproject

Andrew Whitechapel has some interesting articles hosted at Codeguru (create an account):

1. Using the ATL windowing classes
2. To WTL or not to WTL, that is the question

And then an interesting comparison between WTL and MFC:
