Which toolkit to choose for a web GUI (in ruby)

Hi all,

I have written a couple of libs for my Networks project and Would like to provide a web based gui for it.
The fix is that I dont know which toolkit to choose to start with my work.

Secondly I want a toolkit where i can program in ruby only...
ROR is not an option at all,since there is no need for a DB in my project.

I also looked at qtruby,fxruby but they are all just app GUI toolkits ,not what i want.

So can anyone please help me out with this?

Thanks

RoR is not just for use with databases.
