basic object bind from C

[funkaster <funk@...>]

Hi,
I'm writing a small LaTeX editor for Mac OS. I want the user to be 
able to modify the 'toolbar' the way he wants (with the 
buttons/actions he wants). I think that Lua would be perfect for 
that, but I'm facing some problems right now. I've already embeded 
Lua in my app, and I've made a few functions to set/get globals 
(strings and tables). What I want to do is to create some kind of 
"toolbar" object, so that the user can create new instances of a 
"toolbar_item" and then add that to the main "toolbar". What's the 
best way to do this? with a table? creating a new type of data? I'm 
really new to Lua, and I've read all the Reference Manual, is there 
any other good source of information that covers binding C structs on 
Lua?
regards,
