Thats a tough one to answer without more info. Do you have calluses yet? How well do you know where the bar chords are played,ie B chord 7th fret and other places. If you know basic chords more or less than buying Kirks' book plain Talk may be the way to go. There is no law that says you have to play full bar chords and Kirks' book shows you how. You also might want to consider fingerstyle rather than pick. If your comfortable with single notes, this is also an option. There are tons of tabs for finger style on the net. You need to make sure your guitar is set up right for you. If your fingers are hitting adjacent strings, the strings may be set too high or the neck needs to be adjusted. The lower the strings, the easier it is to press down. Try tucking your left elbow as close to the side of your body as you can and angle the guitar towards the wall in front of you to maybe 45 degrees. This makes it easier for your wrist to bend. Move your fretting hand further around the neck reaching towards the 6th string to increase your range. Go here to look for easier ways to finger chords.

An hour a day is fine if your fingers can take it. Once you start getting somewhere and the pain goes away you will find you play more than that just for fun.
Angus Young from ACDC has small hands and he plays very well. He doesn't play full chords and doesn't seem to miss them. His hands are so small that when he does vibrato he has to shake his whole body to make it work because his hands are not strong enough. Down load PowerTab and or
