I think a pretty solid case could be made for the Swordsage, even though he doesn't technically cast spells.
Also, Jack Daniel's got a point: The Cleric basically qualifies. If you remove the whole "priest" flavor, you've got a guy in heavy armor with a medium BAB and proficiency with all simple weapons (which, honestly, does include some good stuff), and the ability to cast a whole slew of combat-appropriate spells. And, of course, this opens the door for the Druid and a whole slew of other divine classes.
