Adding items into JTree

Newbie here need help designing a form using NetBeans 5.5.

Is there a document that details all the components available in Swing e.g JToolbar, JTree, etc...

For instance, after adding a JTree object, how does one add additional nodes or edit the default nodes?

How does one change the icon of a toolbar buttom to display common file open. file save, etc.....

TIA.

Klaus
