No, my bubbles are not tooltips. They will be created by the programmer with a
function like this:

    gtkx_bubble_new(GtkWidget destwidget, gchar *text, gint type_of_movement, gint
type_of_destruction);

and once created, they move around the screen by a timeout function until the
bubble meets the condition of the type_of_destruction (it can be, for example,
bubble_clicked, bubble_mouseover, bubble_out_of_screen, bubble_out_of_window, etc.
)

The main purpose of them is to alert the user of certain validation errors in
widgets, in a more convenient way than dialogs with messages. They will also be
used to show information about the widgets, and a widget will be able to have more
than one bubble at the same time.

Anyway, thank you very much for your information.
When it is finished, it will be part of gtkwidgexts
