I don't even understand what you're asking for here.  You want the
playlist code to do this for you?  To my mind this is something better
implemented in a plugin.

Read the introductory documentation for gtk. There's nothing special
about using gtk within rhythmbox.

Which playlist parser?  What sort of playlists are you talking about?

The database really isn't built for this sort of thing, so you're
going to end up just iterating through the entire thing. This will be
slow.

If you ask specific questions I can answer them. I can't answer "I
need some help".
