Barbarian Macro help

Hello guys. I guess I'm too dumb to understand macros  and i'm asking for help creating a  Barabarian Macro that woudl combine Reckles Attack and Great Weapon Master.  Somthing that would roll 2d20-5 to hit, had a text bouble and would auto ad the 10 to weapon DMG. Could you Macrowizards help me please ? 

Far easier to just create a completely separate weapon for it, on the sheet, and include those modifiers in the attack bonus and damage fields.

this is one that I came up with watching youtube videos lol where it says character enter in the characters FULL name, and where it says abilitymod or proficiency just add the attributes from your character sheet. /em swings with his Warhammer! Reckless, Great Weapon Master! [[2d20kh1+@{Character|abilitymod}+@{Character|proficiency}-5]] and deals [[1d8+@{Character|abilitymod}+10]]
