Addin: Is it possible to make JFRAME/JPANEL as child of any libre office windows XFRAME or so?

Hi We are developing an addin where we have many Java dialogs. We want to show them inside Libre Office window or make them child of LibreOffice windows.
Is it possible to make JFRAME/JPANEL as child of any libre office windows XFRAME or so?
Please suggest

This is still unsolved for me. Can any one suggest how to make a Java Dialog as child of LibreOffice application from an extension.
