Creating editor window for weapon management

I'm trying to create custom editor window which will allow us to create and manage a list of different available weapons. Each of my games weapons is represented by my WeaponVO class:

Code (csharp):

1. [System.Serializable]
2. public class WeaponVO{
3.     public string name;
4.     public GameObject prefab;
5.     public GameObject pickupModel;
6.     public enum Slot { Melee, SideArm, Main }
7.     public Slot slot = Slot.Melee;
8. }

I want to represent the list of weapons in the editor window as an array:

Code (csharp):

1. using UnityEditor;
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class WeaponEditor : EditorWindow {
6.  
7.     [MenuItem ("Window/Weapons")]
8.     static void Init () {
9.         WeaponEditor window = (WeaponEditor)EditorWindow.GetWindow (typeof (WeaponEditor));
10.     }
11.    
12.     public WeaponVO[] weaponList = new WeaponVO[50];
13.    
14.     void OnGUI () {
15.    
16.         EditorGUILayout.Space ();
17.         EditorGUILayout.BeginVertical ();
18.  
19.         foreach(WeaponVO w in weaponList){
20.             // Serialize object here somehow?
21.         }
22.  
23.         EditorGUILayout.EndVertical ();
24.     }
25. }

It seems there is no way to serialize my WeaponVO class so we can input new weapons. Is there anyway to do what I am trying to do?
