Linux servers are popular because they are reasonably stable,
reasonably secure and cost less in licence costs. A windows client can
connect to a linux server.

I don't really understand what your question is asking, because admin
tools are not programming languages. You can't write a program in an
admin tool on Windows either.

As far as writing applications in linux, you have lots of options,
java, php, .NET (using Mono), python, even using the API with C, etc,
you may be able to use Wine to run a windows app under linux, or you
certainly can use one of the remote desktop clients to connect to a
windows terminal server and run your native windows application within
terminal services.
