There wouldn't be much, if anything, left cremating a betta. You could just dry it out (will not smell once dried) and place it in a coffin of sorts.
Similar to what was said, rather than burying in the ground, you could bury the fish in a house plant, that way the plant will use the fishs for nutients and the fish will in a sense live forever in the plant. You could print out a little thumbnail picture and put it on a stick stand (don't know what to call it - how a note is attached to a flower arrangement).
