Answer 2

You are actually trying to write the application? Or are you looking for an existing application?

Your question is like "how to build a bridge across the Atlantic". If you're really going to be building it yourself, that question demonstrates you are not the right person to do it. If you're actually looking for someone else to do it, you need to provide more details about the job to find the right person.

Same in your case. If you're actually planning to write the Java yourself, we can point you to the next step if you tell us where you are right now and what your skill set is. (Hint: The first step is to learn Java.). If you're looking for a program that's already made, you need to list some requirements in more detail.
