Personally I would not add expensive leather gloves to my list just yet. The gliding club I was used some sort of mylar/dyneema/whatever rope which could easily be handled safely with your bare hands.
Wait and see what type of cable is in use, and what others are wearing. Perhaps bare hands are OK, perhaps just a pair of cheap work gloves from the DIY store.
If the weather gets cold, a pair of windbraker fleece gloves with some rubber pieces for grip may work just as well. They will certainly suffice for the trek from the hangar to the launch point.
