Description beyond the filename? No.
But I'd turn it around and ask "what kind of dissector are you trying to make"? If its a protocol that runs over TCP or UDP, we can probably point you to some of the "simpler" ones to get started. There are also many dissectors for other underlying layers.
Many Wireshark dissectors are developed using copy/paste, it's just a matter of finding what you need to copy. Many times assistance will be in the form of "go look at this dissector as an example", because with 1300 dissectors, "there's an example for that".
packet-PROTOABBREV.c certainly gives you a good skeleton, but the specifics of where your dissector will be called (like over TCP or UDP) can give you a good jump because you can just create a protocol field in the tree and have it show up in Wireshark.
