You will have to create a smile detector by creating a classifier. Approaches that you could follow are SVM, random forests, kNN approaches. You should take a peek at the machine learning library of OpenCV.

Also please look around on the net, I have seen tons of people trying to implement this and solutions been given alot. First simple google search gave me this movie, in comments you can find his source code.
