How do I link a textbox with a date so that I can input mm/dd/yy and in the next box have it read the month ie December?

Question

Basically, I want to know how to do this:
INPUT:  12/04/2014
OUTPUT1: December
OUTPUT2: 04
OUTPUT3: 2014
If there's java scripting involved, I'll need a guide, but I have some programming experience.

That can only be done using JavaScript.
The input date is a character string and needs to be converted to the JavaScript date object, from which the month and year can be extracted using one of many different methods.
var cDate = this.getField("input").valueAsString; // get the date string value;
var oDate = util.scand("mm/dd/yyyy", cDate); // convert date string to date object;
var cFullMonth = util.printd("mmmm", oDate); // get full month text from date object;
app.alert("OUTPUT1: " + cFullMonth, 3, 0);
var nDate = util.printd("dd", oDate); // get 2 digit month;
app.alert("Output2: " + nDate, 3, 0);
var nFullYear = oDate.getFullYear(); // get the 4 digit year;
app.alert("Output3: " + nFullYear, 3, 0);
