Usually, x is the column, and y is the line.

(defun goto-xy (column line)
  (interactive "nColumn: 
nLine: ")
  (let ((lines (count-lines (point-min) (point-max))))
    (cond
      ((< line 0)     (error "Cannot go before the beginning of buffer."))
      ((< line lines) (beginning-of-buffer) (forward-line line))
      (t (end-of-buffer) (insert (make-string (- line lines) 10))))
    (let ((columns (- (progn (end-of-line)       (point))
                      (progn (beginning-of-line) (point)))))
      (cond ((< column 0) (error "Cannot go before the beginning of line"))
            ((< column columns) (forward-char column))
            (t (end-of-line) (insert (make-string (- column columns) 32)))))))
