It would help if you can post some sample data for us to work with. But one possible solution:

select sum(a.A) as 'A'
, sum(a.B) as 'B'
from (Select count(yourColumn) as 'A'
                      , 0 as 'B'
          from yourTable
          where value = '33'

          union all

          select 0
                     , Count(yourColumn) as 'B'
          from yourTable
          where value = '44'
          ) as a

This would work for 2 or 3 different columns. Anything more than that and it becomes unmanageable. If what you're looking for is more complex, we'll need some sample data to work with.

You can get all totals from the same table in a single pass of the table:

SELECT
    SUM(CASE WHEN value = '33' THEN 1 ELSE 0 END) AS count_33,
    SUM(CASE WHEN value = '44' THEN 1 ELSE 0 END) AS count_44
FROM table1
WHERE
    value IN ('33', '44')
