File Downloader

[PingPong]

Can anyone help me make a File Downloader?

What I'm trying to make is actually simple to most of the decent coders but I don't have enough experience to do this....

So what I want to make is a program that download all the files in a folder on a server.
But it has to check to see if it's going to download or not
and to check, what it does it compare 2 files
1) on the program side ( where the program is at )
2) on the server side

so it will read the 2 file
and if the 2 files are different then it will download all the files in a folder on the server and it will also download the file that it compared to with the one on the Program side.

Note* I do not want to download the folder, I want to download what's in the folder, every files inside the folder

And I would like to use a progress bar to show the progress of the download.

I also wanted to make a config file that customize the program

The config file can change the program like
background image
background color
title
size
text ( like labels and button names )
and etc
