You should not create your own login system, you should use the core one, otherwise Bad Thing Could Happen™.
This leads to the question: Why you should need another login form? Which kind of checks you have to perform?

Anyway, you could create a plugin that hooks at the onUserAuthorisation event.
If the user could login, you should return JAuthentication::STATUS_DENIED , otherwise block him returning JAuthentication::STATUS_DENIED
