I would suggest a .22 as your first handgun. Ammo is cheap, and a minimal recoil is helpful when first learning to shoot accurately. Browning Buckmark or Ruger Mk. II or III are good accurate guns, and can be had for a reasonable price.
Once you have learned to shoot accurately, then you can move up to the larger calibres.
If your goal is to have handguns and not care about how well you shoot them, then get whatever you want.
X2 on that one.
If I may be so bold and commit heresy in the New Age, buy a 22 LR REVOLVER, then step up to a semi auto.
When you step up to a centerfire cartridge, again, start with a REVOLVER, 38special/357magnum, preferably the magnum as it will digest both.
There are a lot of excellent quality 38 special revolvers languishing in safes these days.
The 38 spcl and 357 magnums, are amongst the cheapest and easiest to start reloading as well.
Again, go to a semi auto of whatever caliber you can handle or have a hard on for, form there.
The reason I suggest revolvers as first handguns, is that there is a lot less to go wrong. There was a very good reason why most police forces issued double action revolvers and as the RCMP do now, double action self loading pistols.
There is a lot less room for accidental discharges. A well tuned double action pistol, is every bit as accurate and serviceable as any semi auto, maybe even more so. One reason the police forces issue double action self loaders, is because they have large magazine capacities.
Whichever you choose, find someone in your area that has both types of pistols and offer to purchase a few boxes of ammo for an afternoon at the range. You sound like you're on your own. NOT A GOOD SITUATION. It can lead to all sorts of issues that are anything but pleasant.
Just about any of the brand name pistols are almost foolproof. Some balance differently and some feel better in different hand sizes. Some people have small hands and can't hold onto double stack magazine pistols well enough for good accuracy, that's where single stack mag pistols come in.
Revolvers usually start out with grips that fit medium size hands. Most people will eventually add aftermarket grips to fit their needs.
If cowboy shooting appeals to you, take a look at the single action offerings. Pietta, Ruger and Colt clones.
The nice thing about the cowboy action shooting is that their pistol cartridges are also chambered in lever action rifles to go along with the pistols.
