I think he's saying that he didn't learn anything from the tutorials included in Dark GDK.
Tanzim, that's really just about as basic as it gets =P If you had a hard time keeping up with these tutorials, then you may want to take some really basic C++ classes/tutorials to learn that. C++ is far from an intuitive language and it really takes alot to learn it.
As of yet, I don't think there are any books available for Dark GDK, and there are few tutorials. You would have to stick it out and play with the tutorial programs till you understand them, or try and get a C++ basics book and follow that along, then progress to Dark GDK.
Hope that helps,
