A Google search will turn up several. But one of the easiest to
use--and the most flexible--is Picasa. Picasa automatically finds the
pictures on your hard drive (you can tell it where to look if you have
pictures in places it doesn't expect) and choose the ones to go into the
collage. The resulting collage is just an image, and Picasa puts it
into a specific directory. You can also save a copy wherever you want
on your hard drive.
From the Picasa Help:
----------
You have total artistic control over your collage content and layout.
Experiment with six different collage types in the hands-on collage
creation screen. To create a picture collage, follow the instructions
below:
1. Select the photos you'd like to include in your collage.
2. Click the Collage button in the Photo Tray or click the Create
Photo Collage button in the folder or album header.
3. On the collage creation page, use the Settings and Clips tabs to
control the appearance and content of your collage:
Collage Style
Settings
Add more photos
4. Use the buttons above and below the collage to help select and
arrange the photos included in the collage. To remove a photo from the
collage, select the photo in question and click the Remove button above
the collage.
5. When you're satisfied with your work, click Create Collage.
Alternatively, click the Desktop Background button to create the collage
and set it automatically as your computer desktop image. Once you've
created your collage, you can share it with friends by uploading to
Picasa Web Albums, emailing, or printing it in high-resolution.

You can specify the page size (either choose from the built-in pages or
define your own) and background, and choose from these methods of
arranging the pictures in the collage:
----------
You can choose from six different styles of collage using the top
drop-down menu on the Settings tab:
1. Picture pile: This collage looks like a pile of scattered
pictures. You can drag photos around the collage, bring a photo to the
top or bottom of the pile, and adjust the scale and angle of each photo.
Click an image in the collage and the wheel will appear on top of your
selected image. Adjust the scale and angle of the photo by clicking and
dragging the wheel button.
2. Mosaic: Picasa automatically fits your photos into the page.
Unlike the 'Grid' collage, the pictures are not aligned into neat rows
and columns.
3. Frame mosaic: You can create a mosaic of your selected images, all
surrounding one prominent center image. You can change the center image
by clicking your desired center image, and then clicking the Set as
Frame Center button.
4. Grid: All of your selected photos are arranged into regular rows
and columns.
5. Contact sheet: Your photos are arranged neatly as thumbnails.
6. Multiple exposure: Your selected photos are superimposed over one
another. You'll see the best results for this collage if you use fewer
images.

Grid appears to be what you are asking for.
I don't think this is very complicated. The price is right, also: free.
