It is true (per @dfan) that bringing the Queen out early invites attack and wastes the Queen-mover's time. In more advanced play, this is very very bad.
But for beginners, it doesn't matter a bit. Beginners waste moves all the time. It's simply part of (and perhaps the definition of) a beginner. Chances are, you won't know exactly how to exploit the premature Queen even if you chase her around with piece development.
On the other side, move your Queen early and see what happens. Play daring, play dashing, take chances, have fun, and cut some heads. You'll score a lot of wins by being aggressive. And you'll get your head cut some, too. /shrug
Against better opponents, this will not work as well and you'll have to up your game.
