There are several of these in the File Exchange. Just search for tracking or red or things like that.

Yes you are right, but I think that those do not include displaying the coordinates as a function of time, instead the coordinates are displayed beside the bounding box. Thanks

As with almost all File Exchange submissions, you should consider them a starting point from which you make modifications to customize it to what you really want, rather than expect them to work just like you want right "out of the box".

You can use plot() to plot graphics (lines, boxes) and text() or set() to display text on your GUI. You shuold be able to get what you want with some programming.
