Gtk::Window win;

win.show ();
...
win.get_window()->lower ();

win.get_window()->raise ();

window manager specific. can't be answered generically. its up to the
user to configure this.

same answer as 3.

www.gtk.org is the reference site.

set the window to handle button press, button release and motion
events. when a button press event occurs, set a flag to indicate you
are dragging. in the motion event handler, if the flag is set, 
move the win with win->get_window().move (x, y). when the button
release event occurs, unset the flag. its very simple. here is some
sample code that is related to this:

gint
TearOff::window_motion (GdkEventMotion* ev)
{
	gint x;
	gint y;
	gint mx, my;
	double x_delta;
	double y_delta;
	Gdk_Window win (own_window->get_window());
	
	own_window->get_pointer (mx, my);

	if (!dragging) {
		return TRUE;
	}

	x_delta = ev->x_root - drag_x;
	y_delta = ev->y_root - drag_y;

	win.get_root_origin (x, y);
	win.move ((gint) floor (x + x_delta), (gint) floor (y + y_delta));
	
	drag_x = ev->x_root;
	drag_y = ev->y_root;
	
	return TRUE;
}

>7. How can I remove the "title bar" from a window ?

this seems to be about the minimum you can get away with in most
window managers.

win.get_window().set_decorations 
    (GdkWMDecoration (GDK_DECOR_BORDER|GDK_DECOR_RESIZEH));
