How can I dynamically assign prompt and URI to a button in a table?

Question

I've got a VO returning document name, link and a status flag. My resultsTable for this VO is currently displaying 3 fields: 2 messageStyledText fields for the document name and link text, and a switcher that shows a checkbox image or red X image depending on the value.
I now want to put a button into this results table that a user can click to launch a subsequent page where they can fill out those related docs. To do this, I'd like to make the prompt of this button = VO.documentName, the Desitination URI of this button = VO.linkText, and then leave the switcher as is. The result might look somethign like this:
<Form 838C> X
<Form 1952> \/
<Form 1234> X
In this case, Form 1952 ahs been filled out, the others not. Users should be able to click one of the buttons to launch a subsequent page where they can fill the form.
I found code to walk through a VO results set using an iterator, you'll see that below. Now, stubbed in these 3 steps below:
--set button dest
--set button label
--determine loop end
I can't see how to do this. I already have the table, so can I walk through the results set and access the results table at the same time?
I need to be able to set each of the buttons to the right Label (Prompt) and then set each button to the appropriate destination. Here's what I have so far: Thanks in advance!

// We use a separate iterator -- even though we could step through the
// rows without it -- because we don't want to affect row currency.
RowSetIterator deleteIter = vo.createRowSetIterator("deleteIter");
if (fetchedRowCount > 0)
deleteIter.setRangeStart(0);
deleteIter.setRangeSize(fetchedRowCount);
for (int i = 0; i < fetchedRowCount; i++)
row = (LANLSupplDocsSummaryVORowImpl)deleteIter.getRowAtRangeIndex(i);
// For performance reasons, we generate ViewRowImpls for all
// View Objects. When we need to obtain an attribute value,
// we use the named accessors instead of a generic String lookup.
// Number primaryKey = (Number)row.getAttribute("EmployeeId");
String formPage = row.getMeaning();
--set button dest
--set button label
--determine loop end
break; // only one possible selected row in this case
// Always close the iterator when you're done.
deleteIter.closeRowSetIterator();

Thanks Guaravv,
I'm unable to get this to compile. Here's the errors I'm getting, followed by my controller code. Thanks again!
