If you're on anything but the most ancient of systems, libudev is what you want for the first step.

If you're on something from this decade, udisks will do all of this for you, too. You'd need to watch the org.Freedesktop.DBus.ObjectManager interface on /org/freedesktop/UDisks2 to see when new filesystems turn up.
