There's only a suggestion for the Witch Class in the DMG, and a spell list for her, but the actual class isn't fleshed out in detail:
The Witch. A staple of fantasy literature and fairy tales, the witch dabbles in many kinds of magic - minor illusions, spells dealing with health or life, nature-based magic, simple divinations, and spells that alter the shape and appearance of things - but excelt at just a few. Hence, her list is somewhat limited but it containts wizard, cleric and druid spells. She casts spells as a sorcerer, using the sorcerer's Spell's per Day table (see page 52 of the Player's Handbook) and her spells are based on Charisma. The witch's spell list is designed with the following considerations in mind.
Cure spells: Only the weakest of these, and the witch doesn't have the cleric' ability to cast cure spells spontanously. The witch isn't blessed with a cleric's (or druid's) plethora of healing spells but she can offer a little aid to those she favours
Illusions: Only through the middle levels. A witch can trick her foes, but not to the extent a wizard can.
Divinations: Only the straightforward divinations, such as clairvoyance/clairaudience and scrying, and not even all of them.
Charms: Many. A major feature of this class.
Form-Changing: another strong point for the witch. From alter self to shapechange, the witch has most of the spells relating to changing her (or someone else's) form
Nature: From speaking to animals to controlling the weather the witch dabbles in this type of magic, if for no other reason than she usually lives a secluded life in the wilderness.
No flashy spells: Anything from a lightning bolt to a wall of fire to Bigby's hand spell is right out. The witch's archetype doesn't suggest overt attack spells or spells that create massive magic constructs. She doesn't summon monsters, place wards, or teleport from place to place. Her magic is subtle.
Miscellaneous: Spells such as whispering wind, Leomubnd's tiny hut, bestow curse (and a few other curselike spells) and a few communication spells round out the list.
((it goes on listing all the spells sorted after spell level, but I can't quite bring myself to type them all in right now, and I'm not sure if you need them, with the above explanation?))

Here's a homebrewed class of the Witch:

Witches could be emulated on this server by picking a sorcerer, and then following the above to the best of your ability. Possibly mixing it with a Favoured Soul for five levels or so, for a little healing oomph.
Otherwise, witches in my perspective is just another layman term for a female wizard/sorcerer, and often a derogatory one at that. Least it's in Rashemen where a witch is a symbol of pride and authority.
Hope that helped somewhat!
