the alcohol in beer is created when yeast consume sugar. there is probably not enough fermentable sugar (if any) in non alcoholic beer to create alcohol, so adding hops and yeast isn't going to help your situation.
if you're thinking about adding sugar to n/a beer and trying to ferment that, that sounds gross and i'd advise against it. bakers yeast sprinkled into a bottle of apple juice would probably be a million times tastier, even if you're not a cider fan.
if i was you i'd check out ciders, wines, and mead. you can get juice and honey where you live, right?
edit: this stuff
gets rave reviews, uses mostly available ingredients (with the exception of wine yeast) and packs a wallop.
