You can use Workflow Rule Field Updates for that. The Workflow Rule will determine when the checkbox is checked, then set the appropriate value in the picklist.
As a note, if the record can only have 1 picklist value, why not use the picklist directly instead of checkboxes?
And, if multiple checkboxes can be selected, you won't want to store the 'collected selections' in a multi-select picklist since that data is not usable.
