DialogWindowwithoptionalclosebutton

Is there any chance of having the QDialog version of a window being able to be added with an option to include close button optionally. I have a requirement to show a window without and controls on titlebar.
I still requite a titlebar to allow window to be moved on desktop.
I will also need to stack these windows upon each other in my application and set the window to top most window.
