Window Inside window

So I have this window, i was wondering if it is possible to put another window inside the scrollbar same as the one outside , so i can use the toggle buttons as menu inside the scroll bar to open windows as the one i already have

an this the scrip i have

using UnityEngine; using System.Collections;

public class SkinTest : MonoBehaviour

{

 public GUISkin thisAmigaGUISkin;

private Vector2 scrollPosition = Vector2.zero;

 public bool doWindow0 = true;
 
 

void DoWindow0(int windowID)

 {
     scrollPosition = GUI.BeginScrollView(new Rect(10, 20, 685, 380), scrollPosition, new Rect(-300,20, 665, 6750));
     
     
         
          GUI.backgroundColor = Color.green;
      if (GUI.Button(new Rect(-300, 22, 140, 18), "Mesa De Los Panes"))
         GUI.ScrollTo(new Rect(0, 1157, 100, 20));
      
      
      GUI.EndScrollView();
     
         
     }
 void OnGUI() {
     
     GUI.Box(new Rect(10,8,145,35), "Menu Del Santuario\nOn/Off");
     
     doWindow0 = GUI.Toggle(new Rect(10, 15, 145, 30), doWindow0, "");
     
     if (doWindow0)
         GUI.Window(0, new Rect(10, 44, 700, 500), DoWindow0, "Basic Window");
     }
