Narrative:

While practicing touch and go landings; another pilot flying aircraft Y announced his intention to enter on a 45 degree entry to runway 20 at pwt. I continued in the pattern announcing my position at all phases of the pattern. While on the downwind I heard [the aircraft Y pilot] say he was on the 45. I announced turning base and then final. I opted to go around and heard someone warn me about an opposite direction aircraft on final. I continued the go around. I then saw traffic directly opposite to me approaching runway 02. I avoided him while on the upwind at 300 feet AGL.I was on my 3rd circuit with others having been in the pattern. I announced my position and continued the go around avoiding the traffic and clearly continued to announce my position. The pilot executed a low approach to runway 02 and continued to fly northbound not talking on the radio. I continued in the pattern announcing my position at every phase of flight. I tried to talk with the pilot but no answer.
