Are you planning to use any base malt? You're not going to get many--make that any
--fermentables out of that. Neither of those grains has any diastatic power
, which means that they will not be able to convert their starches into sugars. I'm at work right now and don't have access to my copy of Beersmith, but if it's telling you you'll get alcohol with just those ingredients, that's because it simply uses a certain percentage of apparent attenuation to calculate FG (and therefore alcohol).
Also, I would strongly suggest scaling *way* back on the black barley, to about 1-2 ounces for a five-gallon batch. I haven't tried using large quantities of it myself, but everything I've read indicates that much more than a few ounces (in a standard batch) will impart acrid and unpleasantly bitter flavors to the finished product.
I hope this doesn't come across the wrong way, but you may be interested in Designing Great Beers
