I don't know whether you can get freeware for this. And, to do something yourself would require lots of work, and it could still be cracked (commercial products can also be cracked, I'm sure).
You should also take a look at legal protection. For a start, register your software at appropriate places (of course, I don't know where that would be in Indonesia). That would give you a good start if you find someone illegally copying your programs.
