Sounds achievable, given some patience, mechanical aptitude and a couple of special tools.
Easy+cheap option A front wheel is relatively common and can be sourced used cheap. If you can find a complete one that suits the bike, just buy it. Most bikes have an Over Locknut dimension (or OLD) of 100 mm, meaning the horizontal gap between the insides of the fork's dropouts. You may have to realign brake pads too. Make sure the replacement wheel is the same diameter as the old, could be any number of sizes.
Easy, more expensive Buy a brand new wheel of the right diameter for this bike. It will very likely be an aluminium rim instead of a steel rim, but that will result in better front braking. Make sure you get the same size, to reuse the existing tyre and to match the front rim brake.
Harder If the hub itself is dead/dying, you can fit the other good parts to a replacement hub. There are a lot of numbers, and they all have to match to be a good fit.
- OLD needs to be the same, else you might need to shim things.
- Number of spoke holes needs to match whatever the rim has. Its likely 32 or 36 holes, guaranteed to be a multiple of 4. You cannot safely miss any holes in the rim or the hub when lacing.
- Flange size - this relates to the length of the spoke that is required to match the rim size. An identical hub makes this so much easier - if you get something radically different then you might need a whole set of new spokes and nipples too. That adds up.
It could work to source a replacement hub from a used wheel that can't fit directly, perhaps a damaged rim or similar.
Buying a hub off ebay or similar is also a valid solution, but prices can vary wildly especially if it was unusual, superlative, or historic.
Once you've got a hub, assembling it should be no harder than building any other wheel from scratch. The nipple spanner is vital. Some way to "true" the wheel, which might just be using the bike grame's front fork and a couple fingers. If you get into the axle, then you'll need at least one cone spanner of the right size. And a series of common hand tools like spanners and screwdrivers too. Plenty of existing questions go into wheel-building in more detail.
