you can't
If you are playing the original Gold game: You caught either a Missingno. (I'm pretty sure you didn't) or you caught the Red Gyarados. It's sad, but the Red Gyarados in Gold has a horrible glitch in it that has a chance of doing what you just described. If you are playing Heart Gold: I have no idea what happened. The Gyarados glitch does not occur in Heart Gold.
after you complete the Pokemon league and go to the kanto region, a snorlax should be found blocking one of the paths. just play the game and obtain the item that wakes it up for a chance to catch it ;] (if heart gold is the same as gold)
You...don't. Maybe you should learn up a little more, play some of the originals before you play HeartGold. Wow, that's...wow.
wild Pokemon are less likely to appear if you play it while walking around
