command button controlling a range of dates

Hi,

I would like to accomplish the following:

1. Have a command button that opens up a popup window.
2. Popup window is to have a calendar where you can select multiple
dates (or two calendars where you select start and end date).
3. Popup window will also have three radio buttons, with a value
assigned to each choice.
4. The selected date range will show up on the worksheet with each
date filled out with a number corresponding to the choice made with
the radio button, with each date having its own cell.

Am I trying to do too much with excel?

Thanks.
