Question

i would like to add an additional button with a small icon to the right of an item in a JTree.
can this be done? if so, how?

You will need to CustomCellRenderer which implement TreeCellRenderer, and attach it to JTree.

In your CustomCellRenderer you can put button and icon.

JTree tree = new JTree(rootVector);
TreeCellRenderer renderer = new CustomCellRenderer();
tree.setCellRenderer(renderer);

Check this example: (referenced above code from here)
