dvars

hi guys,
wondering if anyone can help me. i want to change a few dvars in t6m for visual purposes. i know that dvars such as timescale are possible in trainers and what not. the dvars and values i would like to change are:

r_lightTweakSunLight 22
r_lightTweakSunColor 1 1 1
r_skyColorTemp 25000
r_dof_bias 0.1
r_dof_enable 0
r_dof_tweak 1
r_dof_viewModelEnd 0
r_dof_nearBlur 0
r_dof_nearend 0
r_dof_farBlur 2.5
r_dof_farStart 0
r_dof_farEnd 250
cg_fov 80
cg_fov_default 80
cg_fovScale 1.125
cg_gun_x -0.65
r_lodBiasRigid -1000
r_lodBiasSkinned -1000
r_fog 0
cg_drawCrosshair 0
cg_overheadNamesSize 0
cg_overheadRankSize 0

if anyone could point me in the right direction or even make a tool for us, that would be insane! im wouldent even know where to start in creating a trainer like program myself :c
