Just as a rough, off the cuff answer, cuff answer, try the following.
Beware that you should not modify the list of children.  Also, it does
not return the children's children, etc.

#include <Xm/Xm.h>
#include <Xm/DialogS.h>

void
GetChildren (shell, num_children, children)
Widget		shell;
Cardinal	*num_children;
Widget		**children;
{
	Arg		args[10];
	Cardinal	cnt;

	*num_children = 0;
	*children = NULL;
	if (!XtIsComposite (shell))
		return;

	cnt = 0;
	XtSetArg (args[cnt], XmNnumChildren, &num_children); ++cnt;
	XtSetArg (args[cnt], XmNchildren, &children); ++cnt;
	XtGetValues (gw, args, cnt);
}
