If you do not have a prior sqldev on this machine , ignore this dialog and close it.
SQL Developer is a tool which enables you to access a database. Without a database, there's no much use of it.
Therefore, as you asked which username, password and SID you should enter, make sure that there's an available database you could connect to. If there's none, you can install it on your computer.
I'd suggest you to go with Oracle 11g XE which is easy to install (requires several NEXT clicks) and use. The same (download) page contains documentation, just in case you need it.
