Web Forms :: Creating A Small Pop-up Window?

Here is the general idea of what I am trying to accomplish.Upon page load of the aspx, I am dynamically creating a table (that is populated by database information), one of the columns in the table will display a "NotePad" image. When selecting this image, I need it to make a borderless small window pop up with a blank text box inside of it. The user will be writing notes and information in this text box and then selecting a close window button below it to return to the main page. I need to make this as seamless and fluid as possible, so much so that the pop up needs to look like it was still part of the main page when launched. I also will need to require that the user must close the pop up window before returning to the main screen as well.

Using VB.NET, Is there any way to create a pop up window when a specific cell is clicked on (On Click event) , that will display a small (set size) pop up window with it's border but no titlebar, status, menu, etc. That requires the user to click the close button (provided below the textbar) to return to the main screen?I have found numerous posts on pop-ups, title bars, etc, but none have been much help when I try to put it all together.
