A gas hob is possible you would need units and work tops to accommodate the gas hob and oven.
You could remove a cupboard door if you have one at the right height and use that for the oven, however the hob would require a hole cut into the work top.
Worst case you may need to be additional kitchen cupboards to accommodate the oven, and additional work top to house the hob.
You will also require a gas safe engineer to attend to plumb in the gas appliance.
Please let me know if you require any further assistance.
