Actually those tutorials do reference Netbeans multiple times but usually still tell you how to do stuff in code. Once you got a fairly good grasp of how Swing in general works you will likely read each of those when you need it.
For example Using Swing Components has (more or less) in-depth notes on each of the standard UI components and Laying Out Componnents has details about the standard layout managers.
Those are – at least for me – the things I return to the most. And exclusing a very brief touch with Netbeans I never touched its GUI builder again.
