Need to create a popup to load channel mixer preset

Hi,

     I need to add the following process into my script to create channel layer in my active document.

Step 1 : duplicate the current document's background layer copy and open channel mixer and load the preset which i saved in my desktop

Actually i am having three channel mixer presets in desktop which help loads multiple presets to the active background copy layer

eg.(Blue,Green,Red channel.cha) presets are there in my desktop

But actually what i get from script-listener plugin is i can able to load only one preset at a time right now.

But i need to all these three presets to be used for various situations for different images.In some case i would use red and in some case i need blue channel mixer preset.

So is there any possibility to show a popup like which channel preset you want to load based on the user input the script should load the particular preset to the image.

Please help me on this

Thanks in advance
