Yes, this will NEVER work. Resolutions and screens change dramatically 
across different Operating Systems. They even change on the same OS with 
different video cards and screen resolutions.

You need to use a layout manager, if you want an XPlatform application. 
Which one you use is up to you, but for most, I generally follow the 
following pattern.

   Frame Layouts: Layout type BorderLayout
     JPanel1 added to frame as BorderLayout.NORTH
     JPanel2 added to frame as BorderLayout.CENTER
     JPanel3 added to fram as BorderLayout.SOUTH

     Inside JPanel1, add another Panel. Set it to GirdBagLayout, You can 
design using null for layoyt, but change the inner panel to JPanel1 to 
GridbagLayout internally. This way the JPanel1 will retain NORTH 
Locations within the ContentPane of the JFrame.

Do the same for all other Panels. This makes your application or applet 
pretty portable across platforms. Easy to say, hard to teach online.

Look as Paul F. stated at the Layout Tutorials.
