It really isn't that hard to do that, IMNSHO. The hardest part is finding good 'initial' values for timeouts (if the first packet gets lost), since you don't want *too* long if it happens that the link is short. (Been there, done that. :) Once you get the initial 'broad' issues sorted out and understand that packet loss != congestion, the above stack isn't that hard to build/design.
