How to fetch values into a dependent picklist in apex

I have a country picklist in visualforce page and the country names are stored in a custom setting(countries__c), under this I created a field called countrycode__c.
If I select India then in object 'IN'  gets stored.

so in visual force page I am fetching country names
 
public class CountryCodeGeneratorController {

    public List<SelectOption> countryNames { get; set; }

     

    public CountryCodeGeneratorController() {

        getCountryNames();
    }

    public void getCountryNames() {

        countryNames = new List<SelectOption>();

        List<Countries__c> allCountries = new List<Countries__c>();

        allCountries = [

            SELECT  Name,CountryCode__c
                    FROM    Countries__c
        ];

        for( Countries__c country : allCountries ) {

            countryNames.add( new SelectOption( country.Id, country.Name ) );

        }}

Now in visual force page I create another picklsit say states and what I want to achieve is for every country selected I want to fetch the corresponding states. I do not think its required to create a picklist in object design. also where to store the state names. Please let me know how to achieve this.

Thanks
