JS in pop-up window adding a selection option to a drop down menu in the opener???

Is it possible to have a popup window add a value to a drop down menu in the window opener? Here is my secenario:

Page 1: Has a drop down (select) list that is populated from a database query using ColdFusion. Below the drop down list are 3 buttons [add] [edit] [delete]. Regardless of the button choice, a popup window is spawned (Page 2).

Page 2: After either adding/editing/deleting the selected choice from page 1, I want to change the drop down menu on page one and then close Page 2. My problem is that I can't seem to change to options in the drop down menu.

I want to avoid submitting the form because of the validation in place on Page 1. So, if my drop down on Page 1 has 2 value:
[--- Make A Selection ---]
[TCole Design, 123 Main Street, Fairfax, VA 20150]

and I click on the [add] button below, after filling out a form in the popup window, I want the new value to be added to my DB (already done and working) and then I want the drop down menu to update to read like below. Then the popup window will close.
[--- Make A Selection ---]
[ABC Crating, 456 Main Street, Fairfax, VA 20150]
[TCole Design, 123 Main Street, Fairfax, VA 20150]

Is this possible???

Well, I got it working ... sort of. I had to change my submit button to a button that calls a function to submit the form and then I simply have the popup window referesh the form after inserting the record into the database. I can't get the drop down on page one to select the proper value, but the information is now in the drop-down. This will have to do for now until someone can tell me how it should be done.

Putting the function that adds the option item in the main window will fix the error. Then you will call that function in the popup like this:

opener.functionNameThatAddsAnOption(parameters);
