Pilot setup to land via a straight-in to rwy 15 at kbtv. Winds were out of the southwest at about 5 knots. No reports of gust. At about touch-down and as the pilot started to initiate the flare, the right wing popped up from a wind gust. The pilot tried to level the aircraft but the nose of the aircraft started down too fast. The pilot arrested the decent and as he did the nose came up too high. Aircraft started to porpoise. The pilot felt aircraft was descending too fast so he opted to initiate a go-around. Pilot believes he touched down at this point, but maintained the go around. Pilot coordinated with tower for a gear check. Pilot had gear handle in down position but did not have a green light showing the gear was down and could not confirm visually. Pilot initiated the alternate gear extension checklist and got a green light indicating gear down. Tower reported that it appeared that the nose gear was flat. Pilot setup for another straight in approach to rwy 15. It was a normal approach. Pilot kept the aircraft off rwy as long as he could then set the aircraft down softly. As the main gear touched down, the pilot cut-off engines. The pilot immediately felt metal riding on the runway surface. The rest of the roll out was uneventful.
