I've never heard of webadmin. If I needed to find out how any program creates a web page and the docs and forums were no help, I'd grep for words on that page in the webadmin directories and find out what template file the words are in, then I'd grep for the name of the file to see what function called the template, then I'd start modifying that function to see what changes I could make. If it doesn't use templates, the words on the page have to come from somewhere so grep for them to see if they're hard-coded and if you can't find them then they are probably in a database so start grepping the code for database functions like connect().
