operator class text field or label how ?

i have an operator class which is adding several fields/buttons like float , integer into the tool pro panel

but i need to show a value in tool pro panel and change it as other properties are changed

so how can you add a text or field label that can be assigned while the re draw is being done ?

thanks

Feel free to take a look at my RE:Phrase AddOn, Ricky. It shows how to display, edit and update a text field.
