you can run a process (an exe along with command line arguments) invisibly
You can use that to run putty and make it do the command(s) you want.
You can also make putty spit out the results of it's operations into a file
which your application can then read in and you could display that to the
user (one of your initial requirements!)
So yeah, we are getting you, and what you want to do is totally possible.
