Animating a boneless model

Question

Hi folks. I am new to this forum and an amateur programer. I do this as a hobby. Anywho i am looking for a way to use different limbs on a 3d model (.X) an to use them (like rotate them). I made this model of a coastal gun with groups, a platforn, a turret and a barrel and I am trying to rotate them individually. I am not looking for a full give away I know that would be a lot but if someone could put me on a track (like what class of D3DX I could use with my mesh or if someone knows a good tutorial about that) it would be very appreciated cause I have been looking for that for quite a while now. Thanks
