Window Intefrace theme.

Hi, im new in NetBeans.
Im using MS Windows XP Professional, NetBeans 6, JDK 6, JRE 6.

I saw a few Java Desktop Application example videos; always when the guy runs the proyect, the window theme is like a MS Windows Form.

When a i run mine, the color of the window is set to blue, including buttons and background, even if a change the color in the GUI desinger.

Is possible to run a form like a MS Widows Form (the standar color and layout)?

Thanks.

I've alreday searched this issue in forums, with no results.
