no you can not become a gym leader in any game.
you must frist go to seafoam island where blaine is, he is the 15th gym leader, then go to cinnibar island and a character who is behind the Pokemon center will then say that he is the last gym leader, once you have talked to him he will go to viridian city gym, he is the last gym leader. this is for heartgold and soulsilver :) hope this helped.
