Java SE (Java Platform, Standard Edition)

hi guys...im quite new to java swing..i have this problem and hope u can help me with this..
i now creating an Help frame....i want to have it using the hard coding way...now i want to modify the buttons(or clickable thingy) of the Jframe..
These are found at the top right portion of the frame..( like the minimize, maximize and close buttons..)
and i would like to add new button like a question mark like those help frames from other application...
to really understand what i mean, just right click on your desktop and click properties...and u will see a frame/window with a question mark at
the top right...
