Ok I downloaded the nicklist.dll and read the html tut that was with it. Really didn't understand what a lot of it was getting at. Willing to learn though. 
//dll $scriptdir\dlls\NickList.dll Nicklist @window #
ON *:SIGNAL:nicklist_resize: {
if ($4 == 1) dialog -s $1 0 0 $2 $3
else { window $1 -2 0 $calc($2 +2) $3 | drawrect -rf $1 $rgb(81,101,128) 1 0 0 $2 $3 }
}
var %nicklist_size $dll($scriptdir\dlls\NickList.dll,GetSize,#)
window -hp +d @Nicklist-# -2 0 %nicklist_resize
menu @nicklist-# {
rclick { dll $scriptdir\dlls\nicklist.dll Popup # }
}
//echo -a $dll($scriptdir\dlls\NickList.dll,DllInfo,NOT_USED)
