I need to be able to grab/intercept button clicks from a third party application.  So that I can record them & replay the same sequence at a later time.

You need to use a system hook.  A system hook allows a procedure in a DLL (not EXE) to be notified when various events happen in the system, one of which is mouse clicks (I assume by button you mean mouse button).  

Look at the documentation for SetWindowsHookEx()  This is the function that allows you to create the hook.  If you have any questions after reading the documentation, let me know.

I have tired using a system hook, but not enough informaion is returned.
I need to be able to track which button has been click either on a toolbar, the mouse, or Menu items.

ie. If someone clicks on the OK, Cancel, Next, or Previous buttons.

You can use WindowFromPoint() to find the window that was under the mouse.

That gives you the window handle to the window that was clicked.  What you'll do next will depend on what you are actually tryng to do.  (I'm not sure what that is)  I can help you with that, probably, but you have to give me some idea of the goal.  All you asked so far was how to get/intercept the button clicks in another application.  Which I answered, but I'm not sure where you want to go with that.

First of all.  You should not accept an answer until you are certain it is complete and going to work.  I remind clients of that often just in case.  But this time I'm saying it because I'm not sure how much more help I can give you.

You are going to have a very hard time "translating" the information from one computer to the other.  You can find out the window handle of the window that was pressed on the local computer, but that can't be used on the remote computer.  There are some possibilities, though.

Do you have any windows that necessarily correspond between the two computers.  Like is there is one paticular application that is being used on both computers and that the information must be translated between, or is this stuff that must work with every window currently present?  (If so what happens when there isn't a corrseponding window?)
Do you know if the windows will be at the same coordinates?  Or what information do you know that is the same between the two computers?
