I'd go with the revolver for a novice "non gun guy" as you described.
Reasons:
Ammo is cheaper ( = more practice for the same cost)
Less recoil ( = more likely to practice)
Can be shot at more ranges ( = more likely to practice)
Simpler manual of arms
Will be able to handel it and dial the phone
Recoil is less likely to intimidate the wife ( = more likely wife will practice)
Easier to keep near the bedside
Quicker / easier to verify loaded condition
Able to be brought with you to answer that knock on the door at 2 am
Easier to check through the house with
Related to the last: I'm not advocating houseclearing by a single, minimaly trained homeowner. But how often do you get woken in the middle of the night by a sound, or by the spouse saying "did you hear that"? Often we find ourselves checking out a sound that woke us, that doesn't seem (at the time) to likely be a break in. If you have to do that, the gun you brought with you is far more effective than the cannon resting in the bedroom closet.
A shotgun is NOT the best choice for a "non gun person". The recoil is excessive with buck or slug loads, most "training" will wind up being done with skeet loads by shooting at clay pigeons, many shotgun ranges restrict people to "single load" unless shooting doubles (therefore no training on racking in the next shot), and many lightly trained people find it awkward at best to negoitiate their house with a long gun. If there are reasons against the revolver (personal preference, licensing issues) then I'd recomend an M1 carbine or a mini 14 over the shotgun.
