There's usually nothing of vital importance in gvimrc; it's mainly used for configuring user preferences and whatnot. Here's mine, if you're interested:
Code:
" 100 columns, 60 lines
:set co=100
:set lines=60
" Use visual bell instead of beeping
:set visualbell
" Use CSS for HTML conversion
:let html_use_css = 1
" Luxi Mono 8 point font
:set gfn=Luxi\ Mono\ 8
Save it as ~/.gvimrc (don't forget the period) if you want it to affect only the current user. Keep in mind that gvimrc only applies when you run gvim; if you want to configure stuff for vim in general, use .vimrc instead.
You can type
:help gvimrc
within gvim to get more info about how it's used.
