You need not create a listner for oracle, if oracle is installed on your system there will be a listner configures on your system.

It will be available in
controlpanel--->administrati ve tools---------->services

Actually listner is a service which is responsible for interaction between client and server.
This listenser service should be running .
and if u want to create a new user

log in to SYS or SYSTEM or any othere user account which has create user system previlege

then from that schema execute this

[CODE=oracle]CREATE USER USERNAME IDDENTIFIED BY PASSWORD;[/CODE]
it creates the user.

next grant certain previleges

[CODE=oracle]GRANT CONNECT,RESOURC E TO USERNAME;[/CODE]
Now this user can connect and create his objects.
