You'll need the keywords then you can make one using the 'User Defined Language'. If that doesn't have everything you want to do then an external lexer would be the way to go; which would actually be pretty cool since you could then do the different modes as different highlights as well as the keyword highlighting.
I'm actually sort-of surprised that there isn't one already for Scintilla/Scite.
Do a forum search for either of those two options and you should have a wealth of info.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Is there a language color scheme for notepad++ for cisco pix, switch or routers?
If not how would I go about making one?
This was my stab at it, its very sloppy with doubles and missing commands. The Keyword categories aren't exactly logical ether but it works for me:
