I understand completely where you are coming from, and I don't think you should endure any unnecessary pain during surgery if you're not interested at all.
BUT, surgery is relevant to all specialties, and it seems silly to try to avoid a general surgical experience. I hated internal medicine, but I still felt that I needed to experience it as a student.
That being said, it's hard to tell you which subspecialties are the easiest, because that is something that varies greatly among different institutions. Factors such as the presence/absence of a residency, PAs/NPs, whether you'd be inpatient or outpatient, how busy the service is, etc. You could very easily get your butt kicked on ENT or Urology just as bad as on a general surgery service.
It's probably best to ask the fourth year students at your school.
