title: What exactly is Qt and how do I make a GUI using Qt?
body: <p>I have a project in my class which takes a .csv file, parses through the data, and creates graphs based on the data inputted from the .csv file. </p>
  
  <p>My job is to create a GUI, along with 2 others. Our prof told us to use Qt, so I've been researching Qt and noticed that there website wants us to pay for it. I figured there was a free version, which eventually I did find. When downloading I noticed it was 10-12GB, which is huge. </p>
  
  <p>Initially I was under the impression that Qt was a library that could be imported into a c++ file, and now I'm fairly confident that it's not. </p>
  
  <p>Can anyone explain exactly what Qt is, and how I can import it into a c++ file? If it means anything I'm using xCode on a mac, but my group members are using mostly windows, and one person is using Linux.</p>
  
  <p>People didn't seem to find my question very clear. I thought there would be a file that I downloaded and put into the source folder of my project. Thus a simple import statement would do the trick. </p>
  
  <p>I'm fairly new to programming, so I don't know the terminology very well. </p>
