I'm also a guitar noob who learned some easy songs. These songs are pretty easy:
Anyone else but you - The Moldy Peaches
-easiest song I know, 2 power chords, really easy to sing
I will follow you into the dark - Death Cab for Cutie
-just strum it while you're learning and then you can learn the proper picking pattern, a bit more complicated, needs a capo
The Scientist - Coldplay
-4 chords, really easy to play, easy to sing too. needs a capo
What I got - Sublime
-2 chords for most of the song, easy but impressive sounding solo you can learn in 15 minutes. easy to sing.
Wonderwall - Oasis
-retardedly easy to play, I find it harder to sing, needs a capo
You really got me - The Kinks
- if you like power chords this is your song. 4 power chords for the whole song, solo is a bit harder. really easy to sing
