Assuming the exercises are going to be done during breaks from the computer, I'd recommend taking a look at Convict Conditioning. Most bodyweight training programs tend to focus on increasing volume, e.g. hundredpushups.com. In contrast, CC increases strength by progressing to more difficult versions of the exercises.
For example, instead of going from 20 to 100 ordinary pushups, you go from pushups -> diamond pushups -> uneven pushups -> one handed pushups. (I gloss over a few steps).
As long as you can ignore the stupid marketing name, CC is actually a very good program to follow. (Of course, lifting actual weights at a gym might help too.)
