Java - visually drag a swing element

问题:

Is there a similar solution to http://allen-sauer.com/com.allen_sauer.gwt.dnd.demo.DragDropDemo/DragDropDemo.html#PaletteExample but for normal Java applications, i.e. allowing gui elements to be dragged around on a canvas?

Thanks

Yes, it's possible. No it's not trivial.
