How to learn piano by yourself?

I like learning piano and now i can play a few songs. But my problem is I can play on one hand. I am a left handed but I use right hand when I play. In piano, there is a remember button. I learned all the songs from it by memorizing and practicing. But this button only shows how to play with one hand. So where can I look for the way how to play with both hands? Any idea?
