A surrender button has been suggested and rejected many times. In fact, this site used to have a surrender button but it was abused and hence the button was removed. This thread is a complilation of over 100 threads of people asking for Surrender Buttons or Resign Boxes or Forfeit Flags and the exasperated rejections of handfuls of moderators. It's not going to happen.
If you insist on wasting time by starting a unique thread, I insist you read through this one first to be certain your idea has not already been rejected.
No, it won't be added for certain game types (e.g., trench) either.
And no, it also won't be added if there is a minimum round requirement (i.e, the button appears after 50 rounds).
I'd also like to add that no, it won't be added even if the player remains alive for three rounds but has their turn skipped.
Also, note this suggestion involving surrendering armies to teammates
