Well, if you wanted to do things the sensible way...Or you could just, you know, roll a cleric.
Don't get me wrong -- I love the idea of an armored dwarf wizard, but what you've just described is a cleric.

It's actually a bit different from a cleric though. Wizards have a wider array of utility magic and stronger battlefield control, but are weaker at buffs and defense. The dwarf axe-wizard would be more tactical support, less healer.
