This involves the window manager (not available on eg windows), which is
available through libwnck (documentation available with devhelp).
Here is an untested snippet:
WnckWorkspace * current_wp;
WnckWindow * child_wn, * parent_wn;
child_wn = wnck_window_get (
        gdk_x11_drawable_get_xid (gtk_widget_get_parent_window (
                GTK_WIDGET (child_gtk_window))));
parent_wn = wnck_window_get (
        gdk_x11_drawable_get_xid (gtk_widget_get_parent_window (
                GTK_WIDGET (parent_gtk_window))));
current_wp = wnck_window_get_workspace (parent_wn);
if (wnck_window_is_visible_on_workspace (
        child_wn, parent_wp))
        ...
