I have only recently started to play with the ABC format for tunes, but can confirm that it is relatively simple to get to grips with. It is not too difficult to write a conversion from "the dots".
That said - you might not use "dots", so there are other options. Mudcatter Pavane maintains a programme called Harmony, which will (amongst other things) import a MIDI file and output ABC format. You can then post the ABC text by cut&paste into a Mudcat thread.
If you want an online conversion from ABC to MIDI or "dots" there is a useful website http://www.concertina.net/tunes.html. Go to this page and find the clicky to the "ABC Convert-A-Matic", which has a box you paste the ABC into. It then converts it to a MIDI you can listen to and also printable sheet music..

ALTERNATIVELY
Another website - http://tunedb.woodenflute.com/tunedb/ tune_search_ABC_logic.html. This one allows you to search a large database of trad tunes by entering a few notes, either as note names or as Up-UP-Down from the start note. It is a pretty effective system, so might be a better first call rather than asking here.
Best of luck with your tune names.
Quack!
