the process is so easy,there really is no need for a 1 click.
the hardest part is how htcdev tells you to find the required files for adb/fastboot. you can use this file in place of steps 5-8:
mini-adb.zip just download,unzip,put unzipped file on the root of your PCs C drive. open your cmd window(on windows z,click start bubble,type command in the search box),and change to the mini-adb folder by typing:
cd c:\mini-adb
IMO its good to get adb set up and working,and get a little experinece with it,as the rezound is different than most rooted phones,and there are times when you will need to plug in your phone and use adb or fastboot to do things. if you use a "one click" you wont know what to do when these situations arise.
in a nutshell:
1)unlock using htcdev directions. use "mini-adb" file to simplify steps 5-7. be aware that unlocking your bootloader WILL do a factory reset that wipes all your data.

2)temporarily or permanently install a recovery with fastboot by placing the recovery image into the mini adb folder,and use the following comands with the phone in fastboot:
fastboot flash recovery <recoveryname>.img (permanent)
or
fastboot boot <recoveryname>.img (temporary)
3)flash the superuser.zip file in recovery(
superuser)
thats it. youre rooted

if you want to run rooted stock,and dont plan to use your custom recovery much(or at all),id pretty strongly reccomend to NOT insall iut permanently. use the 2nd command above to launch it whenever you need it.
last and not least,you may want to use revolutioary drivers instead of htc sync:
revolutionary/unrevoked HTC drivers
just reading thru htcdev and these directions,it may seem complicated,but when you start doing it,it really isnt. just holler if you have questions
