A GUI Question

Question

How do I put in a button for each day of the calender (done in this code):
for (int i=1; i<=nod; i++)
int row = new Integer((i+som-2)/7);
     int column = (i+som-2)%7;
     mtblCalendar.setValueAt(i, row, column);
I want a screen that I have coded to  pop-up which has tasks for the day. This is the Window I want for to pop-up when I click the button:
package Calender;
