You can try to add the onChange event on selectList to call a apex function which will invoke a method in your controller. The method will need to query all accounts and populate the name into a new List<SelectOption>. This new list will be used by a 2nd selectList in your vf page. Then you should rerender the 2nd selectList.
Please note that salesforce only allows you to query max 50K records in one runtime.
