[SalesForce] How to dynamically add input fields on a Visualforce page

Currently I have created a text box that allows the user to enter a comma delimited list of values that will be parsed and create new records en masse.

I am now trying to re-create this functionality, but by allowing input via multiple input boxes. Specifically, I would like to allow the user to dynamically add/remove new input boxes to the Visualforce layout and submit them all when a button is clicked.

This way, the controller can then create a new record for each input box that has a value in it rather than having to parse a comma-delimited list that may be incorrect.

Is this possible?

The most basic example will be something like the following (haven't tested it, just typed on the fly):

Controller:

public with sharing class YourClass
{   
    public class CustomAccount
    {
        public String accountName {get; set;}
    }

    public List <CustomAccount> customAccounts {get; set;}

    public YourClass()
    {
        customAccounts = new List <CustomAccount> ();
    }

    public void addNewRecord()
    {
        CustomAccount customAccount = new CustomAccount();
        customAccounts.add(customAccount);
    }

    public void insertAccounts()
    {
        List <Account> accounts = new List <Account> ();

        for (CustomAccount customAccount : customAccounts)
        {
            Account account = new Account();
            account.Name = customAccount.accountName;
            accounts.add(account);
        }

        insert accounts;
    }
}

Page:

<apex:page controller="YourClass">
    <apex:form id="form">
        <apex:repeat var="customAccount" value="{!customAccounts}">
            <apex:inputText value="{!customAccount.accountName}" />
        </apex:repeat>
        <apex:commandButton action="{!addNewRecord}" value="Add New" rerender="form" />
        <apex:commandButton action="{!insertAccounts}" value="Insert All" rerender="form" />
    </apex:form>
</apex:page>

It should get you started, at least to get the idea, then you can modify it as you need to.
