Can hip pain be a result of scoliosis? Can any docs explain?

Yes. It is not uncommon for patients with scoliosis to have an "uneven" pelvis, otherwise known as pelvic obliquity. Pelvic obliquity can definitely no tribute to hip pain through a number of mechanisms. Don't hesitate to see a specialist to discuss further.
Yes. However, many people think they have hip pain when in truth the discomfort is caused by the back and not the hip.
