Greencup, I'm a newbie to linux also. Check out this link: http://distrowatch.com/dwres.php?resource=popularity
Of the first ten or so listed in each column, I've found, as a newbie, that Mint, Ubuntu, Elementary, Zorin, & Lubuntu are good choices starting out in Linux. They have very easy to use software centers for adding programs. If you click on any of the distributions (distros) in the list, you can find out more about it. You can also click on their download page, which has a lot of information.
Good luck in finding the best distribution for you.
