Your question is too general. Everything depends on deeper specification. Let me assume (maybe wrong) you trying to choose from two or three languages suitable for your solution? For example Java, .NET and C++. Every language has own pros and cons. For example architecture design,portability,performance,security, libraries availability and support etc. There are also some personal preferences like previous experiences, ability to understand and write effective code,time to learn certain language approach etc. No solution is 'one size fits all' with 100 % compliance of all raised requirements.... So, yes, it does matter.... you have to consider which one you choose to have best fit for your needs, and results might vary over different languages But no, it doesnt matter ....you can create you solution in almost every language
