Offseting position of guiText in relation to mouse

 var cursorImage : Texture2D; 
 var SelectedGUIText:Transform;
 var TextoffsetX: float = 0.1;
 var TextoffsetY: float = 0.1;
 var cursorSizeX : int = 16;  
 var cursorSizeY : int = 16;  
  
 function Start()
 {
     Screen.showCursor = false;
 }
  
 function OnGUI(){
     GUI.DrawTexture (Rect(Event.current.mousePosition.x-cursorSizeX/2, Event.current.mousePosition.y-cursorSizeY/2, cursorSizeX, cursorSizeY), cursorImage);
     SelectedGUIText.position = camera.main.ScreenToViewportPoint(Input.mousePosition);
 }

I am currently using this piece of script to fix a texture to the cursor position as well as a GUIText, but I want to be able to dynamically change the X and Y coordinates of the GUIText in relation to the mouse cursor using the var TextoffsetX: float = 0.1; and var TextoffsetY: float = 0.1;
