Looking for help designing a character sheet for an RPG I am designing

The game will have four base stats (Attack, Defense, Focus, and Vitality) which will be a specific die type. (d8, d10, d12, etc). It will also have 6 secondary stats (Str, Dex, Con, Int, Wis, Cha) which will have a value from 1 to 5. Interacting with an object, NPC, creature is determined by rolling one of the base stat dies and adding the relevant secondary stat value plus any additional modifiers (armor, feat, spell, etc...) 

That sounds like an easy project (though the bit you've added in brackets at the end hints at a bigger project). Check in the character sheet request thread stickied at the top of the character sheet forum. Also if the system is simple, you dont necessarily need a character sheet. You can use the Attributes and Abilities tab. It's not pretty, but it works.
