Output to file

I have a gui, it gets input from the user, the input will be name, age, email, and number. I need this data to then be written to a file. I have read my book and it refers to a scanner from keyboard. The assignment must be done using a gui so the scanner is completely out of the question! I have created all the input variables and used a JOptionPane to get the information but now im lost on how to get these varaibles printed to a file.

Heres the starting of my code (as you can see i have soooo much more to do) but of course 1 step at a time for me!

To make things easier on myself I have included the assignment details within the code (see part 1 for the output to file). Last week i got lost in the requirements so i figured it best to keep the requirements within the code for ease for me!

What am i missing?
