Hello @Steve2150 and welcome to TAC, yes there are guitars with wider nuts hence a wider neck, that would be a classical guitar. However there are many ways to fret a G chord. Try ring finger third fret low E string, middle finger second fret A string and pinky third fret high E, also know as the three finger G, this particular finger will make transitioning to the C chord a little easier. Hope this helps.
