I am sure there must be better ways. But one long tedious way could be to

-generate 4 (indicator) variables for each response
-by country generate total for each response corresponding to the
above variables, lets say bi (i=1-4)
-generate total obs var for each country bys country:gen new_var=_N

-and within a forvalues loop (i=1/4)
generate percentage_share=bi/new_var if response==i
