I don't know of any wifi tether app that actually works on stock 4.3 (MK4) ROM. As far as I know, you will need to be rooted and flash a stock deodexed ROM and flash the hot spot hack or flash a custom ROM that has it enabled already. There was a wifi tether app that people claimed worked on the stock 4.2 ROM but I'm not sure if it required root permissions or not. I would just root and flash a custom ROM or a stock deodexed stock rom then flash the hot spot hack from LorJay's thread in development forum. It's the best way to accomplish what you're trying to achieve in my opinion.
