Two things about this.. One, if you want to "freeze" your app (turn it
into a finalized exe binary that doesn't require you to have Python or
QT installed), use py2exe. The problem with this is that your final
binary will include the Python interpreter, QT, and any other modules
you use so it will be pretty big.

The other thing you can do is run the script with pythonw.exe instead
of python.exe. It will still be a Python script, but it will run
without opening a command prompt.

It does open a new process. But the new process is a child process of
your original script and the first script will wait for it to finish
so that it can get the return code.

In a normal string, \t = tab, so you're actually running the file
"C:	emp\server.py" which doesn't exist. Try using a raw string, double
your backslashes, or use forward slashes instead.
