For MSSQL 2000 (should work on all the rest just change provider if needed) :

procedure CreateDatabase(WindowsSecurity: Boolean; Username, Password: String);
var
  ConnectionString: String;
  CommandText: String;
begin
  if WindowsSecurity then
    ConnectionString := 'Provider=SQLOLEDB.1;' +

                        'Initial Catalog=master'
  else
    ConnectionString := 'Provider=SQLOLEDB.1;' +
                        'Password=' + Password + ';' +
                        'Persist Security Info=True;' +
                        'User ID=' + Username + ';' +
                        'Initial Catalog=master';

  try

    try
      ADOConnection.ConnectionString := ConnectionString;
