Please explain about the error. Where is it? When does it happen? Is it compile time or execution time or logic.
What is the program supposed to do?
One BIG problem I see is that you don't use a layout manager.
Also please use code tags when posting code. See icon above, to right.

JInternalFrame should be internal to some parent frame. typically after creating an internal frame you have something like,
desktop = new JDesktopPane();
// create jinternalframe called say myIFrame
desktop.add(myIFrame)take a look at this link
