Well, as a generic advice on action implementation it's very useful to
look at gok code. For example:

              int x, y, win_x,
win_y;                                         
                Window root_ret,
child_ret;                                     
                unsigned int
mask_ret;                                          
                GtkWidget
*window;                                              
                char
ename[12];                                                 
                snprintf (ename, 12, "b%d%c", button, (state) ? 'p' :
'r');     
                window = gok_main_get_main_window
();                           
                XQueryPointer (GDK_WINDOW_XDISPLAY
(window->window),            
                               GDK_WINDOW_XWINDOW
(window->window),             
                               &root_ret, &child_ret, &x,
&y,                   
                               &win_x, &win_y,
&mask_ret);                      
                SPI_generateMouseEvent (x, y, ename); 

So gdk_display_get_pointer() should be perfectly fine. Other mouse code
gok-mousecontrol.c should be useful too since it would be nice to
implement mouse movement as well.

Btw, Marius, do you think there is sense to create gnome-voice-control
specific mailing list to avoid spreading of discussion over many places.
I can setup one on berlios for example and we'll subscribe David and
others interested.
