If you want an easy run, get either
10 strength and 10 dexterity and use a longsword (very easy)
16 strength and 10 dexterity and use a claymore (easy)
24 strength and 10 dexterity and use a zweihander (kinda awkward)
invest everything else into vitality and endurance, try and keep vitality 10 or so points higher. Upgrade your weapon as you go through until you get +10 and when you get to New Londo upgrade your weapon to lightning. Easiest build, high endurance allows for pretty much any armor in the game without killing mobility and the vitality is overkill for survival, the three weapons stated have the best movesets out there and are easy to use, I'd recommend the zweihander for PvE or if you decide to go PvP try the longsword, with high stamina it will kill pretty much anyone from stunlock.
Go for pyromancy aswell, it's free (except attunement slots, but you can get quite a few with less than 20 attunement) and has no real requirements. A super flame hand thingie +5 (from Blighttown witch) has massive magic adjustment and can allow pyro spells to smash for huge damage.
