I've shot a limited number of handguns myself, and here's my general impression, recoil-wise;
Glock 17 9mm; Snappy, quick recoil, wants to flex at the wrist
1911-chassis .45 ACP (not sure of brand, a fellow shooter let me have a courtesy magazine with it); very smooth, manageable recoil, as has been described by others, more of a push backwards
Beretta 92 and Taurus 99; these seem to fall somewhere between the snappiness of the Glock, and the push of the 1911, it both pushes backwards and rises, but it's controllable and not snappy
Glock 10mm; *VERY* snappy, much moreso than the 9mm, somewhat unpleasant to shoot
Ruger GP100; .38Sp had a snappy recoil, but not painful , quick muzzle-rise, .357Mag had at least double the snap, a quick, whippy recoil, and a concussive muzzleblast
.44 Magnum; *MAJOR* recoil, both backwards and up, not so much snappy as a very insistent push backwards and up, and a very noticeable shockwave from the muzzleblast, I loved the power of this one, but hated the recoil
If I had to reccomend one of the firearms from the above list to let an aspiring shooter try, I'd go with the Beretta/Taurus 9mm, as it had the most manageable recoil, and the weight of the gun soaks up a good deal of the recoil
