A lot of people use a strap that ties around the headstock, to give the guitar better balance. Not very stable, though.
If you're going to start drilling holes in a new guitar, I would search for a pic on the web of a similar style acoustic to see where the button is mounted.
Once you drill a hole, it's permanent. Proceed w/ caution.
It needs to be placed where the guitar will hang comfortably, and the screwhole needs to be sized accordingly. That is, the drill bit should be about the size of the
shaft of the screw, not the threads. This is going to be your "pilot hole", to allow the screw to go in w/o splitting the wood.
If you're uncomfortable doing this,
by all means wait until you can take the guitar to a shop and have it done. It's a pretty lousy feeling knowing you've screwed up an axe, and I speak from experience.
That being said, here's a pic that may be helpful.
Again, I don't recommend trying this unless you're confident of your ablility...
not trying to be a downer here, just don't want you to mess up any axe, much less a brand spanking new one... OK?
