The PDB creator could be re-written in any language, once you figure out the DB format.

Keep in mind that the app relies pretty heavily on the way the database is structured, and vice versa. You would have to have three levels of playlists before you hit songs, and only three. To get what you want (your playlists replicated on the Palm) you would have to re-write the app itself, and depending on how your playlists are set up, major database changes, too.

See this post to understand why different views would be difficult the current way Palantir does things.
