Enid isn't all that far from me. You have more trees and a little more humidity, but we should be able to grow the same roses. If you're up for a road trip, go to Roses Inc in Tulsa and you'll be able to see the roses in bloom and make a good choice. TLC in OKC has a good selection also.
My strongest recommendation would be to buy Easy Does It.
Next choice would be Cape Diamond.
Belinda's Dream is another safe bet.
For red roses, try Super Hero, Champlain, Linda Campbell, or Kardinal Kolorscape.
Yellow, try Julia Child or Sunsprite (or the improved version, Sparkle and Shine)
Iceberg grows well, has a great scent, if you want a white rose. Milwaukee's Calatrava also has a great scent.
The Austin roses grow really well in Oklahoma without any spraying, but you will need to prune them back or most of them grow huge!
Rainbow Sorbet is a healthy, colorful rose that stays in bloom all summer long.
Seminole Wind is a beautiful rose that needs no pampering. It may be sold as Rosarium Uetersen.
