most likely not. A software of that design would require some hefty programming and I can't imagine there being a freeware option. You could definitely try looking here,

I know with Chase there's an SMS option for transactions posted. See if that's offered with your bank.
Otherwise, I would recommend using the mobile web interface. I'm sure it'll work if you have a data plan. The trouble is you'll have to log in every time. My credit union supports it and I've used it successfully in the past.
