 void Start()
     {
         Screen.orientation = ScreenOrientation.LandscapeLeft;
     }
     
     
     void OnGUI()
 {
     Vector3 V = Camera.main.WorldToScreenPoint(gameObject.transform.position);
  
     if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube1"))
         {
             //do something
         };
 
     if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube2"))
         {
             //do something
         };
 
     if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube3"))
         {
             //do something
         };
     
     if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube4"))
         {
             //do something
         };
 
 }

You are on the right track. You need to convert the world coordinates for each cube to screen coordinates. Try this:

 void OnGUI()
     {
         Vector3 V = Camera.main.WorldToScreenPoint(cube1.transform.position);
         if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube1"))
            {
              //do something
            }
         
         V = Camera.main.WorldToScreenPoint(cube2.transform.position);
         if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube2"))
            {
              //do something
            }
         
         V = Camera.main.WorldToScreenPoint(cube3.transform.position);
         if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube3"))
            {
              //do something
            }
      
         V = Camera.main.WorldToScreenPoint(cube4.transform.position);
         if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube4"))
            {
              //do something
            }
  
     }

Note, your code will anchor the upper left corner of the GUI.Button to the center point of the object. To anchor them on centers, you will need to offset V by 1/2 of the button width and height before making the GUI.Button() call.
