Creating simple moving water surface

I’m very, very new to Blender and am completely overwhelmed with its features. Basically, what I’m doing is researching the best way to put a moving water/liquid surface into a Flash project. The moving water I’m looking to create should look similar to that seen on this page: http://www.blackberrypearl.com/.

Is Blender best suited for this or am I looking in the wrong direction?

You could check how Cog does it (http://www.cogfilms.com/). Another option would be to use the wave modifier (http://wiki.blender.org/index.php/Manual/Wave_Modifier). Or you could try fluid simulator (http://wiki.blender.org/index.php/Manual/Fluid_Simulation) for more advanced approach.
