If you operating system is MS Windows you could write a VBScript program which would run via Windows Script Host. Just write you script and save it with a .vbs extention and doubleclick it to run the script.
Also Java is free but has a much steeper learning curve.
Her is a very simple VBScript example:
'************************************************************************* 'Script Name: SquareRoot2.vbs 'Author: Jerry Ford 'Created: 11/22/02 'Description: This script demonstrates how to solve square root 'calculations using VBScript's Builtin Sqr() function '*************************************************************************
'Initialization Section
Option Explicit
Dim UserInput
UserInput = InputBox ("Type a number", "Square Root Calculator")
MsgBox "The square root of " & UserInput & " is " & Sqr(UserInput)
