I prefer to answer on the IM forum rather than the mail list, so that
people can search and see other peoples answers.  However...

YES
  convert close.png -crop 16x16+0+0 +repage first_button.png

See ImageMagick Exmaples Crop

If you want to append the first button, this may be easier...

  convert close -crop 16x16 +repage \( -clone 0 \) +append new_image.png


This uses Tile crop to separate all the buttons

Duplicates the first button (using a older method)

then appends them together again
