This is quite easy. To bind the window to the door, give the door and the window a targetname, and enter this line below your level waittill spawn command in your map .scr file :

$windowtargetname bind $doortargetname

Now the window should move in conjunction with the door. Also, [url=http://users.1st.net/kimberly/Tutorial/customwindows.htm:c374c]here[/url:c374c] is a tutorial on creating your own window textures for the game.
