You should be able to pick it up fairly quickly. I can't read music, but I bought several RHCP tab books and there are plenty of websites that help out with learning songs. I can play quite a lot of the chili's songs, particularly under the bridge, but I don't really have anough time to practice them and learn many others. The way I learned was to use the tab books, but also to learn lots of chords because then you can start playing your own thing. It also trains your wrist and you quickly learn good positioning.
