It's impossible without some insane hack, and probably not even then. Oshawott didn't exist when the game came out. If you want Oshawott you'll have to get Black or White, they come out in the US in like a week. And then I think you could trade your SoulSilver Pokemon into that game through Pal Park, if there is one in them.

Ash's Oshawott will not evolve.
No, but if you have a Ditto, and others have an evolution of Oshawott (Oshawott, Dewott, or Samurott), then you could trade a pokemon for that evolution of Oshawott. Then you must leave Ditto and the evolution of Oshawott in the daycare together for a while. Then talk to the day care man and he will give you the Oshawott egg.
Oshawott is a Water type pokemon.
Actually, you don't have to catch oshawott you can get it as a starter in pokemon black and white. Starters: Tepig Snivy or Oshawott.
