Welcome, welcome. You'll find a lot of help here. Good people who are more than willing to answer any and all questions. I haven't playing all that long either and I found that learning some of the 'cowboy chords' at first really helps. They are relatively easy and it'll give you some confidence to keep going.

BTW, that's cool that your wife encourages you to play. Always good to have a support system in place. Good luck and check out the myriad of lessons found here. I don't think you can come up with a question that these fine folks can't answer for you.
