Using Ruby on Rails to edit a script?

Is ROR a good fit if I want to edit and expand on a developed script
like RoundCube( )? I'm planing to edit it for my
business as an order/transcript application.

If anyone is interested this link is what I want to make.

Thanks, I think I'll stay with php and have a few modifications made,
then get a price on having it written in ROR.
