Create software to create english words from random list

I want a software which create alphabets from domain list. Like [login to view URL] (result should be money) [login to view URL] (result should be arthritis) [login to view URL] (result = make money online) Basically, i want to sort out alphabets from domain names. Ignore numbers in it. The final list will contain 50000 domains. I want software, where i paste all domains, press "start" button and as a result, i see alphabets which are present in domain names. At this time, i am not sure which platform to chose. I am open for suggestions. It can be .net, java, php or any other option. If you have any other question, please feel free to ask. Thanks
