which OSS product would be easiest to learn that is xPlatform

[James McDonald]

I want to open a csv file which has column headings and rows of data...

eg.

COUNTRY,CITY,MODE,ISP,PHONE#,etc,etc
United Kingdom,London,Analog,Demon,012345678,
United States,Washington DC,Analog,AOL,023456789,
Australia,Sydney,Analog,Bigpond,0345678901,

then feed that into the gui with each field being a drop down list that 
filters i.e. if you select United States it filters all the remaining 
fields so you only get records that have United States in it.

and finally you only get a list of phone numbers for each local ISP's 
POP... which you then pass to your dialler program....


What sort of cross platfrom product could do this? and be familiar to 
someone like my self who has created heaps of little windows VBA form 
apps....
