To access UNIX server from Tk application running on Windows

Hi,
I am new to this forum and this is my first post.

I want to know that if I make an application in Tk (version of Tcl to create GUI) in windows and want to run to UNIX server, is it possible ?
In other words, can I access a UNIX server through a Tk application running on windows ?

Thanks in advance

Yes you can access. You can make use of any existing protocols [Like SSH, Telnet etc] to talk to Linux server. Expect is a one more application [Add on to Tcl] which can be used to automate the tasks.
