How I may use WTL (http://wtl.sf.net/) which based on ATL in Pelles C?
WTL isn't for C++?
PellesC is not C++, only C.
Anyway PellesC IDE supports wizards (that you can write yourself). The following link shows one.

Maybe you can convert part of WTL code in a PellesC wizard code?
I'm sorry, you can't do that.
WTL is C++, Pelles C is not.
In fact, WTL is ATL dependant. And ATL is licensed and only works against Microsoft compilers.
So you better stand away from WTL. If you're interested on a good library for Windows programming, don't care about portability and you understand lots of C++, my recommendation goes to Dev-C++ and SmartWin++ (google it)
