Are you actually talking about HTML frames?  If so how are you planning 
to submit from a button that isn't inside the <form> tag?  Well I guess 
you can do it with JavaScript - perhaps you've already thought about this.

Anyway, none of us ever use this kind of frames so I'm not sure exactly 
what kind of issues you might run into there.

What I would suggest is to split the form up into smaller chunks and 
present it as a wizard so the user can be guided through it - 200 fields 
is a lot to put on one page.

If there is some reason you need to have such a big form, you could 
maybe use an IFRAME to split it up but keep it on the same page.  I'm 
never quite sure which browsers support them though.

Can you clarify a little more the problems you are having?  It isn't 
clear to me from your message exactly how you are approaching this or 
what the problem is.

Using a subcomponent should be as easy as doing:

self call: MySubComponent new.

in an action method if you're calling it, or:

aRenderer render: mySubComponent.

in a render method if you want to embed it.  But like I said, I'm not 
exactly sure where you're having problems.
