Thread: code with problem in layout and scrolling

I have written a code, and some extracted from netbeans for fixing a textfied and buttons for java swing program...
But the textfield is appearing .. but buttons appear after i hover with mouse.
and the same time it is not scrolling also...when i included Jscrollbar...
Important thing below the buttons i have some paint functions to performs... my window will come around 1300 * 900
or more than that...
For that i need to scroll the window.. but i am not able to ...
i am pasting the code can anyone solve the code for me...

PS... some of the variable which weren't used in the piece of code were used in the later half of the code...
Please do reply asap
