Not specifically for CS:GO, but when I used to play MMO my push-to-talk button is one of the thumb buttons on my mouse. It worked perfectly.
This is what a lot of people do, including myself. However if you're being competitive it's worth noting that mapping functions to your mouse buttons can put off your aim slightly when you're using them.
If you're using WASD and not using shift of CTRL for anything they make quite good push to talk keys, providing you have good dexterity in your pinky finger.
in CSGO shift is bound for walking and CTRL is bound to crouch, both of which are fairly necessary. So he'd have to rebind one of those.

Sure by default, but there's nothing stopping you changing them to something else.

purely aesthetics...
cs:go is one of the few games which truely has no p2w.
