The query is wrong among other things.

proper: Select $kolumna from $tabela limit 1

You can also use an offset, reference the manual at
http://dev.mysql.com/doc/refman/4.1/en/select.html

Another thing is, if you are *always* going to want just one result, not
only should you use the proper select, but you should also limit your code
to only ask for 1 result:

$wynik=mysql_query($zapytanie);
$wiersz=mysql_fetch_array($wynik,MYSQL_ASSOC)
echo "<option value=$wiersz>$wiersz</option> <br />";

notice the lack of using a "while" statement, which is not appropriate for 1
result queries.
