Just in case Yeti's comment didn't make it clear, it's still important
to yield control of the program back to GTK once the progress window
is shown, otherwise nothing appears to happen. So your code might look
like this:

do_long_task_step_1(struct task_params *p)
{
  gtk_widget_show(p->progress_window);
  g_idle_add(do_long_task_step_2, p);
}

do_long_task_step_2(struct task_params *p)
{
  /* do part of the task here */
  g_idle_add(do_long_task_step_3, p);
}

do_long_task_step_3(struct task_params *p)
{
  /* finish up the task here */

  gtk_widget_hide(p->progress_window);
}

For file/device I/O, you would use something like g_io_channel, so you
wouldn't need to rely on g_idle_add.
