I was wondering is there any tutorial on how to create a FrameWork?, i am getting used to use some of them but i am very interested on seeing how they work, and how the desicions for one approach are related.
I have been reading and i found the following tutorials, but is there any other you know?, other languages like python, PHP or Ruby?

Although it is not geared towards the languages you mention, there is this book: http://www.amazon.com/Framework-Design-Guidelines-Conventions-Libraries/dp/0321545613
