ScreenPointToRay can handle the instantiation of an object at your current mouse position.

Like in this example:

var Prefab  : GameObject ;

function Update () {
    if (Input.GetMouseButtonDown(0)) {
        var ray: Ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        var hit: RaycastHit;

        if (Physics.Raycast (ray, hit))
        {
            var instance : GameObject = EditorUtility.InstantiatePrefab (Prefab);
            instance.transform.position = hit.point;
        } 
    }

}

And for the GUI stuff I'd suggest starting here:

Use the next buttons to navigate the entire section and once you've read that you should be able to handle the GUI menus easy peasy ;)

Update: Make sure to use EditorUtility.InstantiatePrefab in order to maintain the connection between the prefab and the new instance. With regular Instantiate you will get no connection, meaning changes to the prefab are not applied to the instances.
