Cleric/Figther is good choice. Or go for full cleric who worships war god (war domain gives profiency and weapon focus for deity weapon for free and most war gods use greatsword, greataxe or longsword or bastard sword) and focusing on combat buffs than heals (or cure spells like cure blindness). Then multiclass to figther later on for nice feats. In low level as human you get 3 feats to play with as cleric, 6 as figther. You usually do not need more than 3 feats to be good in combat (and as said war domain gives weapon focus for free).
One example I made my char war cleric he had; Weapon Focus [Greatsword] (domain bonus), Power Attack, Cleave, Improved Iniative.
