SQL Help with change multiple columns into a single column

Question

I am wanting to create either a new View or a new Table based on the following original table:
Original Table:
Fiscal Year
Account
Budget_Amt_January
Budget_Amt_February
Budget_Amt_March
Budget_Amt_April
<etc. for each of the 12 months)
I want the new View or Table to instead be:
New:
Fiscal_Year
Month
Account
Budget_Amount
I can't simply drop the original table, it will have to always exist since it is part of the Finance package, but for ease of reporting against I am wanting to create this new View.
Any ideas on how to go about this?
Thanks!

I had to do something very similar just this week - in my case a record read from a csv into a table, then needs loading into a destination table, and the rows are columns in the csv. I went for INSERT ALL as I also had some conditions.
  INSERT ALL
    WHEN low1 != -998 OR high1 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 1, low1, high1 )
    WHEN low2 != -998 OR high2 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 2, low2, high2 )
    WHEN low5 != -998 OR high5 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 5, low5, high5 )
    WHEN low6 != -998 OR high6 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 6, low6, high6 )
    WHEN low7 != -998 OR high7 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 7, low7, high7 )
    WHEN low8 != -998 OR high8 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 8, low8, high8 )
    WHEN low9 != -998 OR high9 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 9, low9, high9 )
    WHEN low10 != -998 OR high10 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 10, low10, high10 )
    WHEN low11 != -998 OR high11 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 11, low11, high11 )
    WHEN low12 != -998 OR high12 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 12, low12, high12 )
    WHEN low13 != -998 OR high13 != -998 THEN
    INTO partial_profile_temp (search_id, locus_id, low_allele, high_allele)
    VALUES ( search_id, 13, low13, high13 )
    SELECT * FROM bulk_search_load bst, partial_details_temp pdt
    WHERE id = case_number -- only retrieves details for those records that are found in bulk_search_load
    AND filename like 'NETH\_%' escape '\'
    AND processed = 'N';
