To create quest items you use SQL to implement them into your server database as it contains all the server-side content.
Assuming you are using ArcEmu you will create the quest item by executing a query into the "items" table which holds all item templates.
I'll show an example with the
http://old.wowhead.com/item=50432 quest item, which is an objectve of

Entry: Obviously the entry id of your item. Use something unique that hasnt been stored in the db already.
class: Define what type of item you are creating. Consumable/Bag/Weapon(1h Axe, 2h Sword etc.) /Gems(red,blue etc.) /Armor(cloth, leader, mail etc.) / Projectiles, mounts and any other type of items.
Since this is a quest item '12' is used. The quest item class use no subclass so you can skip that.
Displayid: The display id of your item.
Quality: 0 = Poor
1 = Common
2 = Uncommon
3 = Rare
4 = Epic
5 = Legendary
6 = Artifact
7 = Heirloom
Since all quest items is commom quality, 1 is used.
Inventorytype: 0 = Non-Equipped.
Allowablerace/class: -1 = All races/classes
Bounding: 4 = Quest Item. Other options might be, 1 for bind on equip, 2 for bind on equip, 3 for bound on use & 0 not bounding at all.
Quest_Id: This column is used if the item is starting a quest. Since this is an objective of an already started quest so 0 is used.
To link the quest item with your quest you open quests table and put the quest item entry in ReqItemId1-6, then fill the number of count of that item thats required in ReqItemCount1-6.
If you were to use tc or mangos just use their wiki, it's pretty equal and after all just use your common sense.
TC:
http://www.trinitycore.info/Item_template_tc2MaNGOS:
http://getmangos.com/wiki/Item_template(You'll see that it's barely any diffrent between tc & mangos structure)
