Help Converting a VB script to a Plug in

I've written a vb script to enumerate the DCOM launch permissions that I would like to convert to a Nessus Plug in. And I was wondering what woud be the best way, would it be easier to convert it if I convert the vb script to perl then rewrite it in nasl?

I've include the code, basicly the script output is written to a text file.
