simulations

How do I simulate water droplets realistically falling, gathering, and flowing down a window? For example, see http://www.youtube.com/watch?v=4jaGyv0KRPw. In particular, I want to simulate how smaller droplets merge together to form larger droplets that have enough weight to oppose the surface tension and flow downward, leaving a trail of water.

I'm aware of fluid simulation, but how would it be applied in this situation?

I'm a software engineer that's new to game programming so forgive me if this is a dumb question as I don't know that much about game engines.
