This is more or less what I would do. Create your own java.awt.Component that just displays what you want. You might be able to subclass Image and then just draw the formula with Graphics2D operations, and then update in the usual way for Images.

However, you might check out JEditorPane. It might be possible to compose your formula in HTML, and then just use setText. HTML also might be more portable. JEditorPanes are already editable, so you might be able to leverage that instead of do the all the code for editing from mouse click and keyboard presses yourself.
