Regarding generic method

hi all i want to create a method with following requirements and it should be generic. The number of fields is not constant i.e. in some instances there might be 3 fields to be updated in some cases there could be 10 on account object.

The methods should either return the AccountID created or a list of AccountIDs created
  The method should always create the object with all required fields with default values

any sugesion

Use JSON,
Assuming you can populate the fields dynamically in your VF and from JavaScript remoting pass string of object. 
// This JSON can be dynamic based on the requirement add as many fields you want
 [
                     { "Name" : 'Acme',
                       "Phone":"232131"
                     },
                    { "Name" : 'Acme2',
                       "Phone":"232131"
                     }
   ]

// Apex Class method

String jsonString = yourStringFromPage;

List<Account> accounts = (List<Account>)JSON.desearialize(jsonString,List<Account>.class);

Database.SaveResult[] saveRes = Database.insert(accounts);

List<String> accountIds = new List<String>();
for (Database.SaveResult sr : saveRes ) {
    if (sr.isSuccess()) {
        accountIds.add(sr.getId());        
    }
}

return accountIds;
