Answer 1

You can submit the page with a request say "MY_REQUEST" and run a conditional PLSQL block(request equal to MY_REQUEST) and add the PLSQL code there.
If you want to do it without submitting page
<li>Apex Version 4 : Add an id to button (button attributes, id ="MY_BUTTON" ) and add a Dynamic Action fired on click of DOM element : MY_BUTTON , event type would be PLSQL and write your PLSQL code there(add required page items to be submitted in the field)
<li>Apex 3.x and 2.x(works iwth apex 4 too), create an ondemand PLSQL process, call the process from a javascript function(add the item values to session using the ajax request handle) and call the javascript function from the button click( action type: redircet to URL , javascript:function_name(parameter1,parameter2) )
