This is my client code:
(My server is very similar at the moment but I will upload it below this one just in case somebody wants to run it)

I need a way to put this mess in an order. I would like to find an object oriented way to make the client more efficient and then I will use the classes to make an actually server! (I will post another question for the server I guess :P )
Server:

You may ignore the sound or put your own if you are going to run it. The image is a cosmetic logo. Also note that background is used so that text behind it is not visible.
