First off, you need to contact the aviation authorities in the countries you mention to find out what licenses you can train for, and where you can train for them. Thye should have a list of schools which they have approved to provide commerical training.
Second, I'm not sure if CAA courses are being offered in the countries you mentioned, as they are being phased out in the UK, although someone reading this might know better than I.
It might be worth contacting the UK CAA at
Flight Crew Licensing
Civil Aviation Authority
Aviation House
Gatwich Airport South
West Sussex
RH6 OYR
and asking if the countries you mention still train to the old CAA CPL syllabus.
Hope this helps,
