How to insert in a custom Dialog any jquery or asp.net controls?

Hi all.

I am newbie of this wonderful text editor.

I would like to create new plugin that shows a dialog form with within a jquery o asp.net accordion control. On each element of accordion I would insert a combobox (to gather items of combobox for arguments) and then at the selecteditems of the combobox will insert a text into editor.

Does exist a similar plugin?
Can you help me to develop this plugin?

Thanks all.
