var TowerPrefab : Transform;

var totalMoney = 3000;

var towerPrice = 900;

function Update () {

	if(Input.GetButtonDown("Fire1"))

	{

		var ray = Camera.main.ScreenPointToRay (Input.mousePosition); 

		var hit : RaycastHit; 

		if(Physics.Raycast(ray, hit) && towerPrice <= totalMoney)

			Instantiate(TowerPrefab, hit.point, Quaternion.identity); 

		if(Physics.Raycast(ray, hit) && towerPrice <= totalMoney)

			totalMoney = totalMoney - towerPrice;

		if(towerPrice >= totalMoney)Debug.Log("insufficient funds");

	}

}

Lol thats s easy (if i undestanded)
If you want something like a menu for buying towers is easy…Make the menu in photoshop Fireworks whatever and add a gui texture in the game
Make the scipt so that if you press it is actually hapening something…
And then there is your Buy Towers Menu.
