Anyone with Author Apex permission (under Administrative Permissions section in Edit Profile) can create an APEX class or Trigger.
Remember, one can create APEX class and Triggers only on Developer Edition, Trialforce Edition or Sandbox of Professional / Enterprise / Unlimited Edition ORGs only. Production ORGs do not allow editing APEX code.
