"CCP" describes three steps of creating a GUI in Text2GUI (http://text2gui.tinybrain.de).

An example describes it best:

1. Construction

Text: "a checkbox"
Java: JCheckBox checkBox1 = new JCheckBox("Check here");

2. Configuration

Text: "check the checkbox"
Java: checkBox1.setSelected(true);

3. Placement

(assuming there are 3 checkboxes) 

Text: "top-down placement"
Java: return new Sheet(checkBox1, checkBox2, checkBox3).getPanel();

When parsing the input text, every part of it is assigned to one of the 3 phases, making it easy to convert it to code. It's pretty much a simple rewriting process.

Alternative definition of the abbreviation: Creation, Configuration, Position(ing)
