Can I have a PL/SQL code for LOV

Question

Hi,
I apologize for this dumb question. I have been so out of touch with dev (almost 8 years). Plus new to pl/sql.
I am creating a status report application. On the dashboard, I currently have some metrics (horizontal charts). I wanted to expose these metrics based on filter.
I had created 2 filters. The first one will identify the type (Week, Month, Qtr or Year) and the 2nd filter would be based on the type. For e.g. if I select Month as type, the 2nd filter should show May-12, April-12 etc. Once I select the 2nd filter, I should use them to show the appropriate metrics. The metric that I currently have would show all the projects that users have worked on during the week/month/qtr or year (depending on the 1st and 2nd filter).
On the dashboard region, I added a condition to check if the value for both 1st and 2nd filter is not null. This allows me to show the dashboard only if the 2 filters have been selected.
For the 2nd filter, I need to write a PL/SQL code to show the LOV.
I am assuming that the pl/sql would return a SQL query. The SQL query will be based on week, month etc. Is that right?
Thanks

select
        /* Week query */
from
where
and     :p1_filter_1 = 'WEEK'       
union all
select
        /* Month query */
from
where
and     :p1_filter_1 = 'MONTH'       
union all
select
        /* Quarter query */
from
where
and     :p1_filter_1 = 'QUARTER'       
union all
select
        /* Year query */
from
where
and     :p1_filter_1 = 'YEAR'
