Adding user-defined number of text fields.

Question

Okay I am having problems, obviously. I am developing a program where the user will enter X and Y values and the program will calculate the relational data. However, I can't even get a start.
First of all, the user defines the number of pairs of points they want to define. For example, they have 20 points, each with its own X and Y, so they click on 20 and then okay in the first window.
The next window will then take their answer and display X and Y text fields for as many points as they defined. However, I can't figure out any way to do this.
Feel free to run the program, the problem lies in the method setTextFields(). Help please!
