How can I replace glass on a two door hutch?


I am putting the piece in my bathroom, to put towels in and extra stuff. My bathroom is by the lake style. The door opens into it and knob will hit it, so I need to replace the glass and I rather not use chicken wire. I thought maybe some kind of thinner boards going across lengthwise with paint. Also the bottom doors also need something. It's in bad shape needs a lot of attention, any idea at all on the piece are greatly appreciated Thank you in advance. Please disregard the mess, remodeling.
