Tranning is not very diffcult, but it spend long time (at least one week, depend on which computer you use), Opencv provides state-of-art tools for trainning. Check this link: http://docs.opencv.org/doc/user_guide/ug_traincascade.html
Samples is very important, you should prepare samples as many as possible. Maybe you need write a simple annotation tool to create samples.
