menu windows?

[Sinalma]

hi, i'd like to show only the items, save and quit windows and erase status, equip... so i tried editing the scripts taking away from the window_menu and i think some others too but it wont disapear, the max i can do is make it into a useless bottom in which nothing happens when pressed or a grey bottom which i cannot even press.
Is there any script or way to make it possible?
thanks
