Try adding this code before creating any of the scrollbars:

  GtkRangeClass *klass;

  klass = gtk_type_class (gtk_hscrollbar_get_type ());
  klass->slider_width = 40;
  klass->stepper_size = 40;

  klass = gtk_type_class (gtk_vscrollbar_get_type ());
  klass->slider_width = 40;
  klass->stepper_size = 40;


This sets some class variables which are used to calculate the size of the
parts of the scrollbars. I suppose you shouldn't really change the internals
of the classes, but it doesn't seem too bad.

(I'm not 100% sure it works, though. I haven't tested it much.)
