After having carefully selected what handgun she will end up with, get an airsoft replica of that gun. I was able to find an all-metal 1911 airsoft of almost the same weight which makes for very cheap practice. By getting a gas blowback system, I got an airsoft that kicks the slide back just like the real one - and the safeties work the same, the trigger feels very close to the real thing, etc. A high quality airsoft gun (we are talking $100-$150) will allow a person to familiarize oneself with the general operations of the gun without having an actual loaded gun in their hand. You can get targets at places like Walmart that trap the plastic bb's and swing down then reset. BB's do drop over a far distance, so the targets can and should be kept fairly close.
(edit - with a gas or electric blowback, you'll get a little bit of the feel of firing the gun, but with extended practice with grip, trigger pull, etc, a person can develop good habits with an airsoft PRIOR TO any risk of developing trigger flinch - a very real danger in your wife's case. Move up from airsoft to .22 preferably a 22 pistol with the same general ergonomics & action. Work your way up to 9mm or maybe .380 and you can probably leave it at that. You may THINK that $125 for a glorified bb gun is expensive but consider that it will be a non-threatening entrance to shooting, be an excellent tool for teaching, will help avoid forming bad habits early, and think of the cost of buying propane and re-using the same plastic bb's over and over - practically nil. IF the real gun is okay for dry-firing, maybe running through sight picture, trigger pull, and grip while dry-firing, then switching to airsoft is the way to go. Airsoft can make an excellent bridge to the real thing though.)
