Portal Masthead PAR File

Hi,

I want to create a new portal masthead PAR file. i want to modify the entire masthead by changing the location of the logo and other things. I even want to add the tool area into the masthead rather then having it seperatly.

I have no knowledge of java and creation of PAR file from scratch. Can any body help me how i can get started.I have got SAP Netweaver developer studio installed and would assume it is easier to create a PAR file from there.

Thanks in Advance,

Ravi.
