Dialog control like JPanel in UNO awt

Hi,

I am searching for a JPanel in java  like performing dialog control in
Openoffice to contain some other controls inside. And this control model
should be able to make visible and invisible such that the controls inside
it also does the same action. I looked into UnoControlGroupBoxModel, but it
seem to be only a visual component to group controls.
Is the above task possible in UNO awt? If it is possible what control I
should use for that?
Thank you
