I Dont understand why you would want to do that. Fastboot/flashing is a good secure way..
But Still if you want to try out without the Computer. i Hear Flashify- On Google Play will do that for you. All you need is the appropriate Image file In this case the CWM image.
I havent tried it yet. But go ahead and let us know
I Am not sure about a locked bootloader... If you want i can give you steps for the unlocked bootloader

FlashTool wont install the CWM it will just help you get into the bootloader mode..
YOU NEED -
1. Fastboot Drivers
2. Proper CWM Image file.
3. USB Debugging Enabled on your phone
What you need is adb drivers and fastboot.. Search for Fastboot drivers for Xperia M. you will get them easily...
After you get them. Unzip them to say C drive. Open up the folder you will something like py_cmd. Open it up.
You will get the terminal Screen (Command Prompt) Also make sure you boot image of cwm is in the same folder.
Connect phone with usb cable
Type in following commands
1. adb devices (Gives you list of devices). your phone should be listed.
2. adb reboot-bootloader (Your phone reboots)
3. fastboot flash boot [the name of your cwm image file].img (file is transfered)
4. fastboot reboot
And Done
Put this up in hurry. so if you have any problems ping me !
