Getting an inspector button from a MonoBehavoir Script

Unity Engine
1

This placement script it almost perfect, I just need a way to create a button in the inspector . I’d like to do this from within a monbehavoir script, and I have some assets that are monobehavoir scripts with buttons in their inspector so I think this is possible

using UnityEngine;
#if UNITY_EDITOR
//using Rage;
using UnityEditor;
#endif
using System.Collections;
//
//)
	public enum Direction
{
   Horizontal, Vertical, Z
}
//public enum  Direction {Vertical , Horizontal  }
[ExecuteInEditMode]
public class CustomPlace : MonoBehaviour
{//
	public Transform NewParent ; 
	//public Action None;
	public Direction CurrentDirection ;
	public int Blocknum ;
	public GameObject[] Blocks ;
	public GameObject[] Spawned ; 
	public GameObject TemplateBlock ; 
	public Vector3 GotSize ;
  	public float SpawnNum ; 
	public bool GoingUP ; 
	public Vector3 AddPos ; 
	public string BlockName;
	// ;
	
	public bool ModSize ; 
	// if size isn't one
	void OnGUI (){
		
	if(GUI.Button(new Rect(10, 10, 50, 50),"Test")){
		SpawnEm(Blocks[Blocknum]);	
		}
	}
	void SpawnEm (GameObject BlockNow) {
		TemplateBlock = BlockNow ;
		GotSize = 
	TemplateBlock.renderer.bounds.size ;
		
		
		float i = 0 ; 
		while(i< SpawnNum){
			i++;
			
			 switch(CurrentDirection)
    {
			case Direction.Horizontal:
				BlockName = "HorBlock";
				if(ModSize){
				AddPos = new Vector3(GotSize.x*i,0,0);	
				}
				else{
				AddPos = new Vector3(i,0,0);
				}
				break;
				
			case  Direction.Vertical:
			
				BlockName = "VerBlock";
				if(ModSize){
				AddPos = new Vector3(0,i*GotSize.y,0);	
				}
				
				else{
				AddPos = new Vector3(0,i,0);
				}
				break;	
				
				case  Direction.Z:
				BlockName = "ZBlock " ;
				if(ModSize){
				AddPos = new Vector3(0,0,i*GotSize.z);	
				}
				
				else{
				AddPos = new Vector3(0,0,i);
				}
				break;	
				
			}
			
			//if(CurrentDirection.Horizontal){
		//	AddPos = new Vector3(0,i,0);
			//}
			//else
			//{
		//	AddPos = new Vector3(0,i,0);	
			//}
				if(ModSize){
			//AddPos = AddPos*GotSize;	
			}
		GameObject Current = 		Instantiate(TemplateBlock,
				(TemplateBlock.transform.position 
				+ AddPos),TemplateBlock.transform.rotation) as GameObject; 	
		Current.transform.parent = NewParent ; 
		Current.name = BlockName + i ;
		Spawned[(int)(i-1)] = Current ;
		
		}
		
		
		
	}
	 
	void Up(){
	GotSize = 
	TemplateBlock.renderer.bounds.size ;
	}

Found my own solution
Right click and context menu !

 [ContextMenu ("Spawn Now")]
	void Test()
	{
//	IAm.
		SpawnEm(Blocks[Blocknum]);	
		print ("test");
	}
