adding child windows in mfc?

Could anyone help lead me in the right direction to create new child windows in the mfc framework.

I need to create a window, that in turn creates another child window.

I'm not sure how to do this?

Would I use create(), virtual windows, something else?

Any help would be appreciated.

I am not familiar with MDI architecture. Under SDI, one solution is a simple dialog box. Another solution is to derive a class from CFrameWnd and create a view inside of it.
