Thanks for your answer, but I can't obtain what I need. Is the following 
code what you meant?

  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  scrolled_window = gtk_scrolled_window_new (NULL, NULL);
  textview = gtk_text_view_new ();

  gtk_window_set_default_size (GTK_WINDOW (window), 400, 300);

  gtk_container_add (GTK_CONTAINER (window), scrolled_window);
  gtk_container_add (GTK_CONTAINER (scrolled_window), textview);

  gtk_widget_set_size_request (textview, 600, -1);

I had the the following results:
gtk2: the window has a minimum width of 600 pixel
gtk3: the window is 400x300, and so is the textview!

I just want a 400x300 window with a 600x300 textview (or any other 
widget, this is just an example) inside the scrollable.

cheers
