Tom Polakis has recommended the program, WinJupos, which evidently 
predicts Jovian events accurately.

I am not familiar with the WinJupos program, but Tom has evidently had 
good success using it.

You might also look at GUIDE software (by Bill Gray at Project Pluto), 
which is popular amongst the IOTA occultation and MPML (minor planets) 
communities:  http://www.projectpluto.com/

There is also JupSat pro (not free) software:

For just an informal graph of relative Jovian satellite positions, there 
are freebie Windoze (DOS) programs available from Dr. Dan Bruton of 
Stephen F. Austin State U. (SFASU):

Look for Galsat and Satsat:

Also there is JupSat95: http://indigo.ie/~gnugent/JupSat95/

Have fun,
