  insert into xyz

  select v1.cola,
         v2.colb,
         v3.colc
  from (select cola from dummy1 where ...) v1,
       (select colb from dummy2 where ...) v2,
       (select colc from dummy3 where ...) v3;

  But be certain that each of the WHERE conditions returns a single row (beware of cartesian products).
 IMHO it may be easier to spool the contents of dummy1, dummy2, dummy3 to flat files, load them into your favourite spreadsheet, do whatever you want, save it as a CSV file and load with SQL*Loader. It will probably take you less time.
