Here's a tutorial on how to change text in UCCW Widgets:
Step 1: Open the Widget
Your screen should look like this. Click on Background
You will come to a screen that looks like this. Find Static Text. In this example you will be changing Static Text 1 (but you can do this for any of them).
Now you're ready to change the text. In the area that I have circled you will want to scroll the screen in this direction until you see...
Text: This is where you want to change the text! :)
Now you'll want to delete the text you would like to change and add your own custom text!
Done!!! I hope that was explained well enough for those who didn't understand! :)
