Beginner's questions

[Lad]

Hi,
I am a Perl programmer but I miss some things in Perl. For this 
reason I am looking for another, better (if any) programming 
language. Maybe Python would be my choice. Can you please 
answer the following?
1.How well threads are implemented in Python particularly under 
windows?
2.Are there any libraries for working with HTTP protocols that is 
modules that could help download( grab) web pages with GET 
methods and modules for using  also POST method without 
necessity to program these applications with sockets?
3.Are there any libraries for SMTP, POP3 and NNTP protocols?
4. Is there a program for making executable files from python 
programs?
5. What modules , except Tk, can I use for GUI programming with 
Python?
6. Is it possible, in Python, send output from a program to a web 
browser directly or in other words display html file in python 
application?
7. Where can I find a available modules list?
8. What are best tutorials/books on Python?
9. Can you give me  examples of large Python application?
10. Why do YOU use Python?
11. Is it possible to to "talk" to java applets via Python?

Thank you for your answers?
