Hi,
I found something really simple, just three lenses, two fixed sources, paraxial approximation only. But it might do the job for you:

I'm sure there's lots of similar stuff somewhere, just google it...
Best,
zdenek

Beam Four is still a bit more complicated than what I'm hoping for, but 
it's more intuitive and may be useful.  Thanks!

I'm surprised that apparently no one has made a simple graphically 
driven program (--Beam Four relies on entering numerical data) that can 
model ray-tracing with 2 or 3 optical elements.  Something for teaching 
optics, not designing optics.
