You could use a classical guitar "hanger" (a la Willie Nelson)--looks like a saxaphone strap. Only problem is you can't let go of your guitar or it'll spin away from you.
As far as drilling is concerned, you don't have to be a craftsman, only careful. Take the screw from the strap peg you intend to install, and hold drill bits overlaid in front of it until you find a bit size the same size as the shaft of the screw (you should only be able to see the screw threads on either side of the overlaid drill bit). Then measure the length of the screw as it lays in the strap peg: this is how deep you want your hole to be drilled in the heel of the neck. Measure the drill bit to the same length from the tip back, and mark the depth with a piece of tape. Then drill at low rpms to the tape mark. It's important that the hole be as deep as the screw; otherwise, the screw will force the wood fibers apart and could weaken the neck. When I install a strap peg, I squirt a drop of super glue into the hole first (careful to avoid getting it on the neck finish). They never back out from vibration, but can be unscrewed (carefully).
I would venture to guess that your Gibson J200 is much more valuable than the Aria 6 string I got for $200 in 1977 or thereabout. I was tired of tying the string on the end past the nut & under the strings, so in about 1996 I went to a music store, bought a strap button with the screw ( a buck or two)... got my Dad's drill which I'd become handy with and put in a brand new drill bit of minimal size. I figured out the best place to locate the strap button on the dovetail of the neck (as it would be on an acoustic with a strap button on the neck/body. MY did it work well and liberate my playing! I got a leather strap and have enjoyed playing that guitary much more since. If you don't feel okay with a 9/16" drill bit and then confident enought to screw in the phillips screw that holds the strap button... find a local music store than can make certain your Gibson's neck is in good enough shape to handle putting a strap button on it. I spent only a couple of bucks on that strap screw and button but changed my playing forever! Let me know how it goes Ken.
