This does not achieve what you want:

usermod -a -G sudo $user
newgrp sudo $user

change "$user" for your user name.

I wouldn't recommend this, you are allowing "username" to execute any 
command from any location with sudo and without password. This is a 
security breach !

If you want members of the group "sudo" to be able to use sudo add:

sudo   ALL=(ALL:ALL) ALL

Then if you want to grant execution of a SPECIFIC command with sudo 
without a password then add it to the sudoers file:

$user ALL = NOPASSWD: /usr/bin/somecommand --someoption,

Better you can create "Comnd_Alias" with a list of commands. Maybe look 
into the "exempt_group" option, by creating a special group for the 
users you want to be able to run sudo without password.

But IMHO, tinkering with sudo without reading "man sudoers" to grant all 
privileges to some random app seems like a very bad idea to start with...
