well, again no specifications..
but you can use the dialogboxes.. create them and let the user click on one of those 6 buttons..
You have to do some variables for each dialogbox, so create them, show them to the player and create a trigger that notices if dialogbutto X was clicked, and then just perform your action.. it's not that difficult, you should find all triggers and stuff for that..
(sry don't have any time to make a trigger template for you, maybe somebody will do it)
