I'm heading out now so I'm not able to go in and test in order to get specific examples for you but you should be able to set the individual cells in the JTree as editable. This should give you the functionality you're looking for.
At the very least, swing is broken into MVC (model, view, control) architecture so you might need to find the class responsible for the tree's view and change a method there that allows the tree cells to be editable.
Specificly, try something like
JTree myTree = new JTree();
myTree.setEditable( true );
if that doesn't work, try looking into the TreeCellRenderer (the class that handles drawing the tree) and overwriting the interface method it contains (interface should only contain one method) so that the component it returns is editable. You would then have to use your TreeCellRenderer as the renderer for the tree.
public class MyCustomTreeCellRenderer extends DefaultTreeCellRenderer{
    public Component getTreeCellRendererComponent( parameters ){
        return super.getTreeCellRendererComponent( parameters ).setEditable( true );
}//end of inner class
myTree.setCellRenderer( new MyCustomTreeCellRenderer );
You can further change how your CellRenderer works if you need to implement more complex changes. What I've given you here should give you the basis for what you want to do.
Hope this helps.
