Back End Programming Tracks to Come?

I am new to Treehouse. As a young married 22 year old with a newborn daughter that has been trying so hard to find education that is useful in what I'm passionate about has been literally impossible, research for it yourself. Treehouse is changing my life. It is giving me an affordable outlet to learn all that I have dreamed about learning that I couldn't afford at a expensive college or couldn't pick up from typical boring tutorials that have basic text and pictures on sites.

My big question is this, After learning HTML, CSS, JavaScript, JQuery, and then diving into finishing the Ruby and PHP tracks.. what is next?

I want to learn languages for back end programming like;

SQL (further) Java(way different than JavaScript) ASP.Net Oracle ColdFusion ASP Python Perl

Does TreeHouse plan to expand their current tracks to develop people into extensive skill sets?

And even for C++ and C# languages?

I have a vision... a dream... that I have in my pocket. Eventually I will of course have to hire out more than me to complete this goal, because this goal is huge. It requires me to build a Social media site, a socially interactive application, and patents & licenses for a start up business.

I want to learn back end programming to be apart of actually getting the ground work completed. Treehouse is my only hope for this.

Steve pushed to create Applie, Mark to create Facebook, and many more that have created Instagram, SnapChat, Pinterest, Twitter, etc because of a vision they had. I believe this goal I have in mind has never been done before, and that it will grow to be as big in the world as some of these mentioned. But I have a long road ahead to work through;

If Treehouse does not plan to bring tracks for these languages, does anyone know of at least a somewhat decent and affordable option of learning a few of those languages that will really help me develop my dream?

Thank you Treehouse community for taking the time to respond and help me out!
