Basically, what should a GM do to run an adventure for just one player? Thematically, it shouldn't be a problem (many heroes of Appendix N adventure alone), but how to adjust DCCRPG to fit?

Originally, I was planning to just run one level one character through a level 0 adventure, but even if they survive that, how do I make the character in the first place without a normal level 0 funnel?

If you're planning on running a funnel, have the player generate maybe 5-6 zero-level dudes and run him through a shortened adventure. Remember that part of the purpose of the funnel is to trim the characters down to one or so and, since he has fewer total characters than a group of players would have, make sure that the adventure is short enough to do the job without killing everyone.

If you're planning on running a higher level adventure, you might allow him to pick a couple of levels from each of two classes, such as a fighter-wizard. Typical party adventures are often set up to make use of the whole spectrum of specialties that different character classes can provide, but a single class often is missing many of those specialties. (E.g. some adventures don't work well without a thief.) Allowing an easy multi-class system avoids some of this issue.

For a higher level adventure the player could also run a few henchmen or hirelings that are lower level to fill out other classes.

Henchman. Retainers. Meinvt is wise.

Of course, if I only had one player, I'd dust off my copy of Mythic and run DCC 2-player GM-less. I'd also probably have a drinking game set up around rolling a random event in Mythic.

I'm such a shill for that product. DCC too, truth be told.

What, drinking games?

Have a Luck point!

(Is "Luck Point" our secret Thieves' Cant for "slug down a shot"?)

That sounds like a fun drinking game. You could also make everyone that fails a luck roll take a shot.
