The best counters to Katarina are people who can stop her ult. Really, thats it as far as requirements are concerned. Good champions are the like of Diana, Cho, Malzahar (although less so, as his CC requires him to use stuff beforehand or lose effectiveness), Syndra and so on, although any champion with CC works wonders. So beating her later on is rather easy (just try to avoid making huge mistakes).

As for beating her in lane, harass her a lot. Force her to farm with Q, because that can screw her over, and ensures she cant harass you. Unless you made a mistake (or got ganked by Vi), you should be able to avoid dying fairly easy. When she is level 6, be wary of her ult. But if you stop it her damage is so pitiful that she wont be able to fight back.
