[QUESTION] Emulating a site's purpose

I'm pretty big into Twitter, but would like to expand. I have a decent number of followers and presence in my niche. There is a site called "FriskyFriday.me" that counts the number of ReTweets of a user's (Tweet with photo) that corresponds to the hastag #FriskyFriday.

This list then compiles a list, which orders the tweets with the user profile picture and username + the Tweet and the number of ReTweets.

If you are confused of my description, and over the age of 18, check out the site http://FriskyFriday.me.

I'd like to basically design a website to do something very similar, but with all adult hashtags such as #MirrorMonday #TittyTuesday #AssWednesday #FriskyFriday #SexySaturday... etc

I am a computer science major, but I'm not very experienced as of yet. If there is anyone out there that could help me or point me in a good direction, I'd be very appreciative.

Thank you in advance. I will be REPPING and THANKING all people that help and offer what they know as long as it is not common knowledge/basic.

I realize this is a lot to ask in a forum post, just looking for a little help and see if anyone else has done something similar.
