[SNMP4J] creating agent for company software package

[R Tsen]

I was refered to this open-source package for SNMP.  I am a novice to this SNMP and have some questions to implement SNMP4J.

I have read that SNMP can be used not only to monitor hardware but software applications as well.

Our company's software has an application written in Java.  It's installed on the client's server.  
More of our clients are requesting that they want to monitor our software over their network.  

These are my questions:
-SNMP is the way to go?
-How do I make our software SNMP-enabled?  
-What modifications, if any, do I have to do to our software?  
-Would I have to create a MIB for my software which I assume is different from creating an Agent for my software?
-If I do have to create a MIB, do I have to register our company with IANA?
