Don't have Forgotten Realms, but here ya go:
If you mean that the 1st level has to be the NPC Warrior class, then here is a fairly "meat and potatoes" fighter. You can throw javelins until your opponent gets into range, and then draw your sword and charge him.
1st Warrior: Point Blank Shot, Far Shot
2nd, 1st Fighter: Exotic Weapon Prof. Bastard Sword,
3rd, 2nd Fighter: Quickdraw, W-Focus: Bastard Sword
5th, 4th Fighter: W-Spec: Bastard Sword
If you prefer a "pure meelee" type then take Power Attack, Cleave at 1st, and Improved Toughness (from Complete Warrior) instead of Quickdraw at 3rd.
Stats:
Str: 17 (Improve to 18 at 4th level)
Dex: 11 (on the off chance you find a magical tome that increases Dex by an odd number)
Con: 16
Int: 8
Wis: 8
Chr: 8
Skills: Ride (8 ranks), Handle Animal (5 ranks), Intimidate (3 ranks) (If you will never ride a horse, then: Intimidate (8 ranks), then max out either Swim (if your DM is a mean DM) or Jump (otherwise)).
Equipment: +1 Full Plate, +1 Large Shield, +1 Bastard Sword, Ring of Feather Falling, 2 Potions Cure Mod. Wounds, 3 Potions Cure light Wounds, 3 javelins, 12 gp. If you need more money, sacrifice a potion or two.
