In Australia, you can start as a sole trader.
This is a much cheaper solution to starting a company.
It basically means 1 or two people, usually one starting a small business trading with your own name or a commerce name.
The problem with this is all your assets are liable if someone sues you, even your dirty socks.
You probably have something similar in the windy city where you live.
A company requires at least $1000 to start in Australia.
You can buy a company that someone else started and scrapped, you do however incurr the costs of that companies history. This is called a shelf company.
You need a Financial controller or accountant to start a company as well as a director.
You wont be able to afford an accountant when first starting out.
I would imagine your just a young dude, start with a sole trader if you have them in your country, establishing a company is a waist of time until you start to make a $50k+ profit a year, look up your countries rules governing this aspect.
A company is like an entity or person, the company can own assets like a person, and when the company is folded or sued, the assets of the company are liquidated first, sometimes they also seize your own assets if you are accused of malpractice etc..
Once your company gets really large you can float it on the public market and start offering shares. this usually leads to the demise of your control as you will find there are more people interested in squeezing money from your idea/company.
now that the reality has set in, go back to your project and think real hard about your next step.
If no-one gives your an answer to a question you have asked, consider:- Is your question clear.- Did you ask nicely.- Are you showing any effort to solve the problem yourself 
