Human Factors
Flight started normally. All checklists were run with normal responses and aircraft configuration. We [were] cleared for takeoff with a flaps one setting. After airborne; the FO called for gear up. With less than 200 feet AGL; the FO had to apply excessive nose down trim; we got the buffet alert and stall warning indication in the HUD.The takeoff horn never sounded. The FO applied max thrust; I saw the flap indicator was [indicating] zero. I dropped the flaps to position one and the aircraft accelerated and climbed normally after the gear was raised. The aircraft was never in a stall; just close to it. After considerable discussion; the only thing possible is if I had accidentally raised the flaps instead of the landing gear.
B737-700 Captain reported accidentally raising the flaps instead of the landing gear in initial climb; putting the aircraft in a near-stall condition.
