You can go to an autoparts store and buy Duplicolor 1200* paint, or Hardware store and get Barbeque paint. I perfer the 1200* stuff. Don't paint it in the house if you can help it, it stinks up the whole house and can aggravate asthma or allergies.
The glass only has gaskets on each side as stated above.
If you can, paint the stove, and put it in the driveway and start a wood fire in it to burn off the paint stink.
