You want get-buffer-create I think

get-buffer-create is a built-in function in `C source code'.

(get-buffer-create BUFFER-OR-NAME)

Return the buffer specified by BUFFER-OR-NAME, creating a new one if needed.
If BUFFER-OR-NAME is a string and a live buffer with that name exists,
return that buffer.  If no such buffer exists, create a new buffer with
that name and return it.  If BUFFER-OR-NAME starts with a space, the new
buffer does not keep undo information.

If BUFFER-OR-NAME is a buffer instead of a string, return it as given,
even if it is dead.  The return value is never nil.
