Yes, it's a rose - probably a climber - if you can train the canes outwards rather than upwards - as shown by Paul Zimmerman here http://paulzimmermanroses.com/gardening/training-roses/training-climbing-roses-on-a-trellis/ you should get a lovely display of blooms.
Edited to add: roses aren't hard to grow - whoever told you that? Stuff and nonsense and you've got one for free, probably £15 worth there. There aren't many things prettier than a climbing rose on an old brick wall. Give it a go and see what happens
