How can I measure distance and create a bounding box based on two latitude+longitude points in Java?

Question

I am wanting to find the distance between two different points. This I know can be accomplished with the great circle distance. http://www.meridianworlddata.com/Distance-calculation.asp

Once done, with a point and distance I would like to find the point that distance north, and that distance east in order to create a box around the point.

We've had some success using OpenMap to plot a lot of positional data. There's a LatLonPoint class that has some basic functionality, including distance.
