Using EditorGUILayout . ObjectField how do I access the GameObject not Object?

The main item is EditorGUILayout.ObjectField target. I would like to make a script window that I can drab an object into and press a button to add a whole bunch of components to with custom settings.
Right now it seems the targetObject is just type of Object and I can not access its GameObject

I tried various like
targetObject.activeGameObject....
but nothing in the code analyzer or autocomplete is giving me a hint

Code (CSharp):

1.  
2. targetObject = EditorGUILayout.ObjectField(targetObject, typeof(GameObject) , true) as GameObject;
3.  

full code

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. #if UNITY_EDITOR
6. using UnityEditor;
7. //using UnityEditorInternal;
8. #endif
9.  
10. public class SetupToolWindow : EditorWindow
11. {
12.  
13.     public Object targetObject;
14.  
15.     [MenuItem("NERF/Auto Setup tools")]
16.     static void Init()
17.     {
18.         var window = (SetupToolWindow)GetWindow(typeof(SetupToolWindow));
19.         window.Show();
20.     }
21.  
22.     void OnGUI()
23.     {
24.         // sizeMultiplier = EditorGUILayout.FloatField("Increase scale by:", sizeMultiplier);
25.  
26.         GUILayout.Label("Doo stuffff", EditorStyles.boldLabel);
27.  
28.         EditorGUILayout.BeginHorizontal();
29.         targetObject = EditorGUILayout.ObjectField(targetObject, typeof(GameObject) , true) as GameObject;
30.         EditorGUILayout.EndHorizontal();
31.  
32.  
33.  
34.         if (GUILayout.Button("Magic"))
35.         {
36.             if (targetObject)
37.             {
38.                 Debug.Log(targetObject.name);
39.                 Rigidbody rb = targetObject.activeGameObject.
40.             }
41.             // if (!Selection.activeGameObject)
42.             // {
43.             //     Debug.Log("Select a GameObject first");
44.             //     return;
45.             // }
46.  
47.             // Selection.activeTransform.localScale =
48.             //     Selection.activeTransform.localScale * sizeMultiplier;
49.         }
50.     }
51. }
52.  
53.  
54.  
55.  

 

you probably want:

Code (csharp):

1. public GameObject targetObject;
