Which language should I learn to make a modern XMPP client?

Hi, I'm a complete useless lurker who do not know anything about programming, and I want to program an XMPP client :D. I have absolutely 0 competence, but I'd like to know if there is a language preferable to make such things, and if there is a place where I can start to learn. I tried with some basic tutorials and general lessons about programming, but without a clear goal I got bored and stopped after a little while. Thanks in advance for every advice/insult!
