If this works at all, you are very lucky. ;-)

A scrolled window is not a toplevel widget at all, and a
Dialog is a toplevel widget and cannot meaningfully
be reparented as a child widget .

What you want to do is create a Window widget with 

  gtk_window_new (GTK_WINDOW_POPUP);

This creates an "override-redirect" window - one that
won't be seen by your window manager.

Put your scrolled window inside of that, and then put 
the contents inside the scrolled window. You'll have
to duplicate the dialog widget by hand, but that isn't
much of a hardship - the dialog widget just contains
a VBox with a HSeparator and a HBox (the action_area).

Hope this helps,
