Some might also argue that Lady Macbeth is a good wife, in that she sees what she considers to be a weakness in Macbeth and vows to assist him in overcoming this towards his own personal path to glory/power.  In Act I, scene v, she says:

...yet I do fear thy nature

It is too full o' the milk of human kindness

To catch the nearest way.  Thou wouldst be great

Art not without ambition, but without

The illness should attend it.

In the society in which Macbeth and Lady Macbeth live, it would have been a normal, warrior-like approach to life for a man to be hard and ruthless.  So, there is definitely a case to be made for Lady Macbeth having Macbeth's best and manliest interests at heart when she vows to toughen him up.  This determination to see him become the "best" that he can be would, arguably, make her a good wife.

One of the the qualities of a good wife would be loyalty.  Lady Macbeth is certainly loyal to her husband.  She believes that not only Scotland but also her husband deserves to be king.

A good wife is a gracious hostess.  Lady Macbeth again qualifies.  Duncan comments on what a wonderful hostess she is when he arrives.

A good wife also stands by her husband through thick and thin.  Lady Macbeth covers for Macbeth when he freaks out at see Banquo's ghost.  It is Lady Macbeth who explains his odd behavior to the gathered guests.

There you have three qualities of a good wife.  Hope they help you.
