GUI Text Area that Reads / Writes / Saves

I am having the hardest time trying to get this done.

I have a Text file that is blank, That i want to Read / Write too. however, I want the GUI to be able to read it in a Text area, and Edit the Text file in realtime, or a button that would save the changes to a Text file.

Any known way of doing this?

Eric's answer and follow up comment should help you begin.

If you're in standalone player:

import System.IO;

var contents : String = "Write some text!";
var file : String = "somefile.txt";

function Start()
{
    Load();
}

function OnGUI()
{
    // Use contents string in text area. 
    // Have buttons call load and save.
}

function Load()
{
    contents = File.ReadAllText(file);
}

function Save()
{
    File.WriteAllText(file, contents);
}
