Why would you need threads ?

I assume your syntax would look something like this:
===================================================
GtkWindow *window;

window = create_window(); // Creates a GtkWindow with a child
                          // GtkDrawingArea (or whatever you're using)

/* ... */

gtk_imshow (window, x, r,c);
/* pause */
gtk_imshow (window, x.*2, r,c);
/* pause */
gtk_imshow (window, a_beautiful_filter(x), r,c);
===================================================

The only tricky part is to know when is the appropriate time
to create & destroy your window.
