Help with Times Table GUI applet

Question

Hello,
I need help with an applet which inputs an integer from the user and displays the appropiate times table up to times 10 eg; user input 5 - display shows
5 time 1 is 5
5 times 2 is 10
5 times 10 is 50.
I have only managedt o get the display to show one statement eg 5 times 1 - I have tried using a for loop to show the whole table - but unlike a print statement each time the loop goes round it overwrites the data in the display box with the new data - any help would be much appreciated.
Note: it is for a programming course year 1 exercise - so I can only use basic constructs or loops to achieve this. Thanks in advance! Heres what I have so far:
