Hmmm... not sure if this is what you want, but if it is, then the answer
might be (literally) right under your nose ;) Look at the HTML source for
the management screen for a Zope folder. The process to select folders etc
using checkboxes is similar to what you describe...

If you structure your checkboxes as follows....

  <INPUT TYPE="CHECKBOX" NAME="notes:list" VALUE="doe">
  <INPUT TYPE="CHECKBOX" NAME="notes:list" VALUE="rae">
  <INPUT TYPE="CHECKBOX" NAME="notes:list" VALUE="me">

Then the target of your form will get a 'notes' (variable/attribute) which
you can loop over, process etc, Only the values where the checkbox has been
selected will be included in the list. In place of 'doe, rae' me, you could
enter the ids of the objects you want to delete, wame say as the Zope
management screen does.
