Answer 2

Its very much possible to get pressure data. In GTK/GDK you register for all extension events with gtk_widget_set_extension_events()

gtk_widget_set_extension_events(widget, GDK_EXTENSION_EVENTS_ALL);

and you will start receiving move/pressure events as well. The link Olorin posted could be the Qt interface for the same, but I haven't used it so cannot say for sure.
