Good chord progressions, Charlieissocoollike or Julia Nunes style.

I have a friend who I had been talking to, and I mentioned that I had to try to write a song for her. She keeps bugging me to finish it though!!

Do you have any good chord progressions. Maybe something that sounds like a Charlieissocoollike song with a bit of Julia Nunes in it? You're help would be FANTASTIC!!
