Killua is in a intimate relationship with his own brother, Alluka, and their love seem to be mutual. Gon has been dating older ladies on and off for god knows how long, and he not only knows anything about what having a date means and the questionable implications all of his "dates" carry, he doesn't seem to care either.

Whether you like what you see, or agree with it or not, that's another matter, I'm just stating what's there.

As such judging by those 2 pieces of information, I highly doubt they are gonna become a couple.
