What is a easy way to make your own chords with a piano for beats? what should i start to learn to make them my own?

A lot of pop music producers will start with a basic four-chord pattern, I–V–vi–IV.  For example, if you are in the key of C Major, you would play a C Major chord (CEG), a G Major chord (GBD), a A minor chord (ACE), and an F Major chord (FAC).  That is a popular "template" so to speak that can lay down the basic line for you to put other instruments over.  

If you really want to get involved, a little bit of music theory never hurt anybody.  You don't need to know much to get a basic understanding of the way things work.

I hope this helps :)

they are often in theme and variations
