Answer 1

Swing has a built-in control for displaying data in a Tree format called JTree. It also provides a data model called DefaultTreeModel which you can use to store the data. This link gives a pretty good explanation of using a JTree with a data model.

[Edit]:

To answer your updated question, a graph like that could quite well be handled by JGraph which would also provide the data model which seems to work similarly to the Tree model swing provides.
