Post, Like, Comment in Facebook

I am not sure if what I want to do is possible. I want to have a website where someone can login with his/her facebook credentials. After that there is a list (from a database), where the user select to what pages/posts/photos want to Like / Share / Comment. By pressing one submit button at the bottom of the page all that acctions take place. Lets see some example -the first record is to participate to a contest. I must like a facebook page and share a link (urls for fb page and link are in the database) -the second record is to comment a post and say my opition. there is a prefilled text to post (e.g :I like it!"), but I can change it -the third record is to like a facebook page etc I check the actions that I want to do and then I press submit button is that possible? can you do this?
