How to sort posts by views/popularity?

So I have all my posts displayed on the home/main page like a catalog type thing. I would like to be able to sort the posts by views or most popular with a menu item. Is there a plugin that does this or maybe a tutorial? I’m just no good with php no matter how hard i try to understand it, but I’m trying to get this sorting thing done and can’t find anything that can help me. Thanks!
