Suggestion regarding designing of an effect.

I need to create a animated effect like link drop spreading on a blotted paper.
At first i thought of checking shaders, but i dont know anything about shaders,
I tried researching on it for last 3 days and couldn;t find anything, so before i invest any more of my time into it,
i want to know if its possible to create effect like this using shaders or anything. If so please point me in that direction.
