Create a simple Wix install script as per specification below

Just to get me over the learning curve with Wix in fastest possible time. I am after the XML to complete the following tasks which I will later import into Visual Studio to compile an MSI. The objective is to quickly show me synatx of Wix so can incorporate into my own projects. Just do not have time at moment to learn this from scratch. I be using latest version of Wix.

1. Create the following folders
c:\Program Files\TestWix
c:\TestWix\Sample
c:\TestWix\Sample\Subfolder
c:\TestWix Empty Folder

2. Create a SQL Server ODBC connection that will appear in control panel under System DSN tab. Details are DSN name = TestWix server=10.10.10.10 Database=Test Integrated logon=Yes

3. Copy the folowing files into c:\TestWix\Sample
c:\windows\win.ini
c:\windows\system.ini

4. Copy the following files into c:\program files\TestWix
c:\windows\write.exe

5. Create a menu item and shortcut to the c:\windows\write.exe

6. Register a DLL file into the Global Assembly Cache (GAC). Just pretent you have a dll called WixGAC.dll in c:\windows

7. Register a DLL file into the registry as you would with regsvr32.exe. Just pretent you have a dll called Wix.dll in c:\windows

8. Create a new key in the registry with a value. Do not care where or what. HKEY_LOCAL_MACHINE would be fine. Just need a demo of how to create registry entry.

6. Uninstall should uninstall DNS and files (if possible)
